Daily Pick
One deeply researched guide worth reading today.
A practical route through the systems that matter most, written to help new players make confident decisions quickly.
Overview
Gurei is a hand-drawn 2D boss-rush action game from Lobo Sagaz studio, published by Astrolabe Games. You play as Rei, a human spirit bound to hunt ten mystical Kami inside a surreal castle that floats between the human world and the spirit realm. Kill a Kami, absorb its power, and every boss still alive gets harder. Launched July 22, 2026 on Steam, PlayStation 5, and Nintendo Switch simultaneously, $15.99 standard price. Steam Deck Verified, 42 achievements, and the original soundtrack (17 tracks by Santi Castillo, about 27 minutes) released separately in late August.
The review picture as of early November: over 300 reviews, Very Positive overall, recent reviews Mostly Positive. The curve tells its own story. Launch players loved it. The ones who hit the late-game scaling wall write the negative reviews. This guide is mostly about not hitting that wall.

The signature mechanic: dynamic difficulty scaling. Every Kami has a base moveset, and each kill you bank applies a multiplier to the survivors. The same Catfish you flattens as fight one comes back as fight nine with extra phases, new attacks, and arena hazards. Boss order is not a preference. It is the entire game.
Story & Setting
Rei owes a duty. The Kami, ancient entities of nature drawn straight out of Japanese mythology, hold the castle between worlds, and her job is to take them down and absorb what they carry. The presentation borrows from classic samurai cinema: sparse dialogue, hand-drawn frames, fights that read like duels rather than brawls.
Each Kami behaves like its animal. The Catfish is slow and deliberate. The Dove is fast and flighty. The Bull is stubborn, direct, and allergic to being cornered. Defeated Kami follow Rei around the castle afterward, perched on her shoulder, commenting on the world and on each other. Their chatter mixes real gameplay hints with personality banter, so it pays to listen instead of skipping.
Kills also wake NPCs scattered through the castle. They hand out lore, side objectives, and occasional shortcuts. The castle starts nearly empty and fills up as your body count rises, which gives the hub a tangible sense of momentum between fights.
The Hub World
You spawn in a circular chamber with branching paths and zero direction. That is deliberate. Every path leads to a boss, and choosing which one matches your current skill is the core decision.
The hub is compact but layered. Paths loop and intersect, and shortcuts unlock behind cleared arenas. Golden flames mark boss entrances. Bird statues work as orientation landmarks. A save point sits right before every boss room, which matters more than it sounds: it means you can re-tool your ability loadout immediately before each fight with no cost.
First session advice: spend ten minutes just mapping the hub. Intentionally die to two or three bosses. Deaths are cheap and the knowledge is permanent. Knowing where every entrance sits lets you change targets mid-run without wandering.
Getting Started: First 30 Minutes
Your first run is route research, not a clear attempt. Treat it that way.
The starting kit:
- Sword: light and heavy attacks
- Dodge: carries invincibility frames
- Jump: doubles as an enemy stomp
- Dash: no i-frames, covers ground fast
- Wall movement: climb and wall jump
No healing, no defensive tools, no second chances. Every piece of power you get comes from a corpse.
Recommended opener: head left from the hub, descend at the end, go right. That is the Catfish. Two attacks, both slow and telegraphed, shield bash and ground stomp. Aggressive play breaks its shield and stuns it for a five-second damage window. The reward is the Shield ability, the single best defensive tool in the game.
The mistake that kills most new players: treating every fight like a DPS race. Boss health bars in Gurei are long enough that two or three greedy combos will kill you before you kill it. The correct rhythm is dodge, punish with two or three hits, disengage, observe, repeat.
Death is a tool. A failed attempt costs exactly one life no matter how far into the fight you got. Abilities you have earned never disappear. Spend one life watching a full moveset, then win on the next attempt with full health and complete information. This is strictly better than guessing.
Core Mechanics
Dynamic Difficulty Scaling
The system everyone misreads. It tiers rather than scaling linearly:
- Fights 1–3: base movesets. No phase transitions. One or two specials per boss.
- Fights 4–6: phase 2 activates around 50% HP, new specials appear, bosses move 15–20% faster.
- Fights 7–9: phase 3, arena-wide attacks, some teleportation, attack chains extend by one or two hits.
- Fight 10: full moveset, four phases, maximum aggression.
Concrete example from launch players: the Catfish is "simple at the first scaling level" and "notably more robust when saved for the final four." The Snake starts with roughly two attacks early and grows to four or five after several wins. The Peafowl changes how its weapons arrive, an early version offers a choice while a late version brings the full armament.
The strategic consequence: your worst matchup must happen early. Saving your least readable boss for the final slot means meeting its hardest version while carrying maximum run pressure. Route discipline is the game.
Lives System
You start with a small pool of lives. Each boss victory adds one. Running dry ends the run and sends you back to the title screen, with the run's abilities lost but all knowledge (and achievement progress) kept. Lives are shared across bosses: dying five times to the same Kami is fine while you have banked lives.
When you are on your last life against a wall, switch targets. A fresh fight with a different moveset gives better odds than replaying the same failure.
Sacrificial Scout Runs
Because a failed attempt always costs one life regardless of progress, scouting runs are optimal play, not waste. Against any boss you have never fought, especially the Raven (three phases) and anything faced at high scaling, throw attempt one to learn the vocabulary and win attempt two.
The Combat Loop
Strip every fight down to three parts: read the cue, move through the threat, take the safe punish.
- Dodge a named attack, not general danger. A panic dodge spends movement before the attack commits and can park you inside the next hit. Wait for the visual cue, then dodge to a chosen destination that leaves you in readable space away from arena edges.
- Use short punishes until the pattern proves more. Two or three hits, disengage. If a punish that used to be safe suddenly fails, remove the last hit and re-observe. At high scaling the boss may have gained a follow-up. Do not assume your input was bad.
- Stomp only when the landing is part of the plan. The downward stomp commits you to a landing spot. Use it when the ground threat has finished and you know where the boss will be. Above unknown enemies, stay horizontal.
- Layer each new power onto one solved moment. Shield the cue that still causes mistakes, mobility for one specific lane, healing only after the arena stabilizes.
Animation Cancels
Dodge cancels the recovery frames of heavy attacks. Hit, dodge, hit beats hit, wait, hit by a wide margin, roughly 30% more effective damage once it is muscle memory. This is the single highest-leverage execution skill in the game.
Ability Loadout and Tier List
Every defeated Kami grants an ability. Save points let you re-equip freely before each fight, so loadouts are per-boss decisions, not commitments.
| Ability | Source | Use Case |
|---|---|---|
| Shield | Catfish | Absorbs one hit. Mandatory against projectile-heavy bosses. Creates observation time. |
| Healing | Frog | Limited uses per save point. Heal below 60%, not near death. |
| Clone | Monkey | Decoy that pulls aggro. Buy time to heal or reposition. |
| Revive | Cat | Timed second chance on death. Kill the boss before the timer runs out. |
| Scythe Finisher | Snake | Massive damage on staggered enemies. Best execute tool. |
| Air Dash | Peafowl | Full i-frames on a short cooldown. Best mobility tool in the game. |
| Arrow | Dove | Chargeable ranged poke. Damage without commitment. |
| Counterattack | Raven | Return damage on being hit. Strong against multi-hit combos. |
| Spear | Beetle | Long-range melee, slower but safer reach. Charged heavy pierces through adds. |
| Ground Slam | Bull | AOE knockdown, staggers large bosses. |
S-tier: Shield, Healing, Air Dash, Clone A-tier: Scythe Finisher, Arrow, Spear B-tier: Revive, Ground Slam, Counterattack
Loadout combos that carry runs:
- Clone + Healing: the strongest defensive pairing. Clone draws aggro, Healing tops you off. Against any fight with adds, this resets the fight state.
- Shield + Air Dash: the universal survival kit for any boss you have never fought. Shield eats the surprise hit, Air Dash phases through the rest.
- Arrow + Spear: full ranged kit for kiting the Bull, Catfish, and slow-phase Raven.
Boss-by-Boss Breakdown
Catfish (Shield Kami)
Two attacks: shield bash (horizontal arc, dash away) and ground stomp (shockwave, jump it). It alternates shielding and attacking. Your sword bounces off the raised shield, so stop swinging and wait for the drop. Sustained damage breaks the shield and stuns it for five seconds. Slow, telegraphed, and the community consensus pick for fight one. Faced late, it gains a much larger arsenal, another reason to take it early.
Snake (Combo Chain Kami)
Attacks in two to three hit sequences ending in a heavy slam. Dodge the first two, create distance on the third, punish the recovery. Its tells live in the head: rears back to strike, coils to lunge. Getting hit once means eating the whole chain, so if you take damage, dodge immediately and do not trade. Faced early it has roughly two attacks; after several kills it grows four or five.
Reward: the Scythe Finisher. After eight to ten hits any boss staggers, and the Scythe takes about 40% of its bar in one move. The window lasts around two seconds, so commit the moment it opens.
Peafowl (Weapon Kami)
Floating swords and saw blades. Weapons embedded in the arena floor deflect projectiles back at the boss, so positioning near a weapon cluster beats raw dodging. When it charges its AOE (red glow), Air Dash out. Clear the floating weapons by deflecting before you try direct damage, each deflection both damages the Peafowl and removes a hazard. Faced early it offers a weapon choice; faced late it brings the full armament.
Reward: Air Dash. I-frames on a three-second cooldown. It transforms every later fight and wall jumps chain it into near-permanent aerial evasion.
Monkey (Clone Kami)
Summons copies of itself. The original is slightly larger, and killing it ends the fight even with clones alive. Dodge the summon animation (arms raised) to avoid the spawn attack. Charged heavies and Ground Slam clear clone swarms. If you carry the Spear, its charged heavy pierces through the pack and hits the original directly. Community discussion flags this fight as movement-heavy and visually cluttered, which makes it a good early test if crowded arenas are your personal weakness.
Cat (Self-Damage Kami)
The trick fight. The Cat's health drains on its own over time. Your only job is survival while it teleports and dives from above. Dash when it disappears, block dives with Shield, heal between teleport cycles. It teleports to three fixed positions, so learn them and pre-position. Do not chase. This is the only fight where defense is the offense, and new players who try to speed it up just donate lives.
Reward: Revive, a ten-second second chance after death. Generous against most bosses, tight against the Dove and late-game Raven. Several launch players called Cat the strongest first pick in the game: the fight is a pure survival check and Revive converts every later mistake into a recovery.
Frog (Insect Swarm Kami)
Flying insects swoop in patterns, spiders charge on the ground. Prioritize fliers, they are faster and harder to read. Spiders die to a single light attack interrupt. The arena is small, so keep one wall at your back. The insects glow before charging, and the dodge is sideways, not backward. This is the game's only add-heavy fight, and players who skipped it until late describe it as overwhelming, faced early it teaches the crowd control fundamentals every phase-3 fight needs.
Reward: Healing, the run's best sustain.
Dove (Arrow Kami)
The first speed check. Teleports, fires spread arrows, drops AOE zones. Low platforms block ground-level spreads, and wall jumping between them resets your air options, so staying airborne dodges most of its kit for free. Dash toward it on teleport, it usually appears diagonally. Never stop moving, because stillness lets it dictate range.
Reward: the chargeable Arrow. Fully charged shots do triple damage and pierce, ideal for poking during boss attack cycles.
Raven (Three-Phase Endurance Boss)
Phase 1: dash and peck combo. Phase 2 adds feather spread projectiles. Phase 3 adds ground-spike AOE. It teleports after every three attacks, always to one of three fixed spots (far left, center, far right), and a shadow marks the landing half a second early. Pre-position and take two free hits per cycle.
Gameplan per phase: aggressive in phase 1, reactive in phase 2, pure survival with Shield and Clone in phase 3. It opens with a dive, so skip the charged-heavy opener you use elsewhere.
Beetle (Parry Duel)
A straight sword duel. Dashes do not reliably escape its swings, and the fight is won through parries: time your attack against its swing and a successful parry stuns for three seconds. Build the stagger bar (yellow glow around its health) to 100% and the fight ends early, you do not need to deplete the bar. Charged heavy, parry, charged heavy fills it in about twenty seconds.
Tells: sword overhead means downward slash, easiest parry. Sword held to the side means horizontal sweep, wider hit but a harder read. A glow before its charge means do not parry, dodge sideways.
Reward: the Spear.
Bull (Final Boss Candidate)
The tankiest boss with the simplest core, right up until it is your tenth fight, at which point it becomes the most mechanically complex duel in the game. Killing it normally grants the "The Bull" achievement; killing it as your final Kami grants "The Wrathful Demon."
Core attacks (numbers in petals of damage):
| Attack | Tell | Answer |
|---|---|---|
| Uppercut (2 dmg) | Clasps hands, lowers body | Wait a beat, then dodge behind. Dodging early still clips the lingering hitbox |
| Kick (1 dmg) | Lifts leg, arms up | Dodge on sight, it is fast. Jumpable if you want to keep attacking. Cannot break pillars |
| Rock spawn | Rock appears behind you | Turn and break it immediately. Cornered between rock and Bull means heavy damage |
| Pillar | Dust cloud at screen bottom | Obvious to dodge. Watch the boss shatter it later and send rocks flying |
| Jump | Simple leap at you | Dodge to where it jumped from. I-frames do not save you directly underneath |
| Mega jump | Leaps to a pillar, then sky | Debris marks the landing. Side-step and parry it, shield it, or Air Dash through for counter damage |
| Shout (2 dmg) | Curls up, turns red | Wait a second, then dodge. Pushes you and breaks all stones. Often combos into kick |
| Dust cloud | Cloud at its position | Dodge behind and retreat, or turtle behind Shield |
| Rising pillars | Fist slam, lines of dust | Dodge behind or run. Pillars rise fast, then punish window opens |
| Spikes | Dust across the arena, hands lift | Watch the hands, not the dust. Jump the moment they rise |
The universal rule for this fight: never get cornered. A cornered Bull scenario costs roughly three petals in one exchange. Between rock spawns, pillar shrapnel, and wall pushes, the arena edges kill more players than the Bull itself does.
Route Planning
There is no single correct order, and pretending one exists is how players hit the wall. The scaling means every route is a chain of tools: each win should make a specific later fight easier. Three proven frameworks:
Balanced Route (first clear)
| Order | Boss | Reward | Rationale |
|---|---|---|---|
| 1 | Catfish | Shield | Best defensive tool, slowest reads |
| 2 | Frog | Healing | Sustain before difficulty ramps |
| 3 | Monkey | Clone | Pairs with Healing |
| 4 | Cat | Revive | Survival check, safety net |
| 5 | Snake | Scythe | First spike, adds an execute |
| 6 | Dove | Arrow | Fast boss, ranged answer |
| 7 | Peafowl | Air Dash | Mobility before phase-3 tier |
| 8 | Raven | Counterattack | Three-phase endurance test |
| 9 | Beetle | Spear | Parry duel with full kit |
| 10 | Bull | Ground Slam | Slow and predictable with a complete kit |
A tankier variant swaps the opener to Catfish, Cat, Frog, the three survival fights, and banks Revive before anything hard.
Adaptive Friction Route (what experienced players actually do)
- Open with a readable Kami for reliable life income. Catfish or Snake.
- Test your personal wall boss early. Whatever matchup consumes your lives, whether that is crowded arenas (Monkey), aerial tracking (Dove), or delayed timing (Raven), move it toward the front of the run while scaling is low.
- Keep Peafowl out of the final stretch. Its late version brings the full arsenal.
- Re-evaluate after every reward. Shield earned means you can now afford a busier arena. Air Dash earned means revisiting the fight whose tracking beat you.
- Never pick the next boss because it is physically closest. The castle is built to let you redirect.
Speedrun Route
Catfish, Snake, Peafowl, Dove, Monkey, Frog, Raven, Beetle, Cat, Bull. Air Dash, Scythe, and Arrow arrive in the first four fights. No healing until fight six, so this only works if you can near-no-hit the opening stretch. Roughly 20–30% faster than the balanced route when clean.
Step-by-Step Strategies
- Opening ten minutes: spawn, walk every branch of the hub, note golden flames and bird statues. Die once to the Catfish and once to the Snake on purpose. You now have a map, two partial movesets, and full knowledge that deaths cost one life.
- First win: Catfish, jump the opening stomp, three light attacks per opening, break the shield for the five-second stun. Equip Shield immediately at the save point.
- Banking sustain: Frog next. Sideways dodges on glowing insects, one-hit interrupts on spiders, one wall at your back. Healing comes out and every future run gets a safety valve.
- Scout protocol: first contact with any unseen boss is a no-damage attempt. Full health, watch every attack, die once if needed. Attempt two with complete information wins faster than ten blind attempts.
- Mid-run re-tooling: before every arena, open the save point loadout. Shield against Peafowl and Dove. Healing against the Bull. Ranged kit (Arrow, Spear) against slow bosses, defensive kit (Shield, Clone) against fast ones. Thirty seconds of swapping beats a wasted life every time.
- The last life rule: on your final life, never fight your worst matchup. Pick the boss you find easiest. A win banked anywhere is a life earned.
- The Bull finale: for "The Wrathful Demon," leave Bull for tenth. Bring Shield and full healing. Fight in center arena, break rocks the instant they spawn, and never fight with a wall at your back.
Advanced Tips
The first hit is free. Most bosses idle about a second at fight start. A charged heavy lands before their AI wakes. The Cat (teleports immediately) and the Raven (opens with a dive) are the exceptions.
Wall jump resets. Jumping off walls resets your air dodge. In platform-heavy arenas (Dove, Raven), chain wall jumps to stay airborne indefinitely; most ground attacks miss entirely. Stack with Air Dash for near-immunity.
End offense one hit early. Your best defensive upgrade is often ending a punish a single hit sooner so the next dodge starts from a clean state. Buffered sword strings into an incoming cue are the most common self-inflicted death.
Dodge to a destination. The invulnerable moment is only half the dodge. Finish where the arena is readable and the boss cannot pin you on an edge. This single habit fixes most corner deaths.
Life banking across knowledge. Run-level abilities vanish when a run ends, but moveset knowledge persists forever. A scouting death in run two is an investment that pays out in run four. Nothing is wasted.
Stomp discipline. The stomp is a spacing tool first, an attack second. If clones, camera effects, or projectiles make the landing uncertain, stay horizontal.
Secrets & True Ending
Caterpillar spirits. Small glowing collectibles hidden in hub corners, behind false walls, and on out-of-reach platforms. Collecting all of them feeds the true-ending path.
NPC unlocks. Each Kami kill can wake NPCs around the castle. Talk to all of them; some give side objectives and hints, the game tracks your count but never marks them on a map. Backtrack after every kill because the castle changes.
Hidden shortcuts. Cleared arenas open shortcuts back to the hub, marked by subtle visual changes: fading barriers, newly lit torches, opened gates. They make reruns through the hub dramatically faster.
The true ending. The first credits are not the end. The "Honor?" achievement (7.2% unlock, description "Fulfill your duty") requires collecting the caterpillars and clearing a dramatically harder final gauntlet, with a different ending sequence. Plan a dedicated run after your first clear. The bottom of the achievement list, Mastery (3.2%) and Acceptance (2.8%), tracks full-mastery challenge clears beyond even that.
Controls & Settings
Keyboard + mouse: WASD move, mouse aim, left click attack, right click dodge, Space jump/stomp, Shift dash, E interact.
Controller: full support for Xbox, PlayStation DualShock/DualSense, remappable. Keyboard rebinding is partial; some core actions are hard-bound.
Settings worth touching on day one: controller deadzone to minimum (the default makes precise dodges feel sluggish), vibration off (constant rumble during duels is noise, not information). The game is light on hardware; hand-drawn 2D runs at 60 FPS on integrated graphics, and Deck Verified means zero tinkering on handheld.
FAQ and Common Mistakes
1. Hoarding healing "for emergencies." Players sit at 70% HP and die holding full charges. Heal at 60% or below; the next save point refills you.
2. Fighting your wall boss late. Postponing your worst matchup means meeting its maximum-scaled version at maximum run pressure. Move it early. This is the single biggest fixable cause of negative reviews.
3. Using dash as a dodge. Dash has no i-frames and you take full damage mid-travel. Dodge for evasion, dash only to close distance or leave an AOE zone after the blast.
4. Treating the Cat like a normal fight. Its health self-drains. Attacking aggressively just donates lives. Survive, let the clock work.
5. Trading hits with the Snake. Its chains extend on contact. One hit becomes three. Dodge out immediately.
Q: Can I see credits without killing all ten Kami? A: No. All ten are required. Optional encounters and secrets are not.
Q: Difficulty settings? A: None. Route choice is the difficulty setting.
Q: New Game Plus? A: Not at launch. The scaling system provides the replay variety: ten bosses, 3.6 million orders.
Q: How hard compared to Hollow Knight or Souls? A: First-clear difficulty sits around Hollow Knight's mid-to-late boss tier. A max-scaled run where every boss shows three or four phases rivals the hardest optional content in that league.
Q: Steam Deck? A: Verified, 60 FPS native, officially announced by the studio. Also on PS5 and Switch from day one.
Q: Multiplayer? A: No. Single-player only.
Q: How long are fights? A: Two to five minutes early, five to ten late. A first-attempt late-game Raven or Bull can push fifteen.
Q: Does progress persist? A: Achievements and meta-knowledge persist across runs. Only the current run's lives and abilities reset on a run-ending death.
