About THE KULKA
MUTATE YOUR BULLET. FLAP, EVOLVE, SURVIVE.THE KULKA is a one-button bullet-heaven arcade roguelite where your single shot slowly mutates into pure neon chaos. Imagine Flappy Bird colliding with Vampire Survivors.Tap to flap like in a classic flappy game, dodge walls of enemies and stack bullet upgrades until the screen explodes in colour.Fast, focused and replayable – built for tight controls, punchy sound, online leaderboards, challenges and that “one more run” feeling.
CORE LOOP
- Tap or click to flap and keep your orb in the air.
- Your shot fires automatically – destroy enemies to earn XP gems.
- Level up and choose an upgrade to mutate your bullet.
- Survive as long as you can, then try to beat your high score – locally or on global leaderboards.
KEY FEATURES
- One-button gameplay – easy to pick up, hard to master. You only control vertical movement, but every flap matters.
- Bullet mutation system – every level-up adds new behaviour to your shot: split, ricochet, pierce, homing, explosions, lightning, lasers, novas and more.
- Tons of builds – turn your tiny pellet into a bouncing storm, a piercing rail, a safe shield bubble or a swirling vortex of damage.
- Fast arcade runs – instant restarts and quick runs; perfect for short sessions or long “just one more try” evenings.
- Difficulty options – Relax, Easy, Normal and Hardcore presets – from chill flapping to sweaty record chasing.
- Two upgrade styles – classic manual upgrade picks (you choose like in Vampire Survivors) or Flow mode with automatic upgrade choices so you can focus purely on dodging.
- Extra modes – additional ways to play.
- Neon Geometry Wars–style look – clean synthwave grid, bright orbs and clear hit feedback even when the screen is packed.
- Punchy sound design – crisp hits, juicy pickups and satisfying upgrade feedback on both speakers and headphones.
- Flexible controls – keyboard (Space + arrow keys), full gamepad support (Xbox / PlayStation / standard) and touch input; great for PC, Steam Deck and Remote Play.
- Online leaderboards – compete with other players in global Steam score tables across multiple modes and difficulty levels.
- Challenges & progression – unlock new options by completing in-game objectives instead of grinding endless gold.
- Ball Bank – choose your starting weapons, skins and modifiers in a dedicated loadout / armoury screen before each run.
- Marquee in the main menu – see the top players’ nicknames scrolling across the main menu every time you launch the game.
- Steam achievements & Cloud – over 100 achievements plus Steam Cloud support for your progress.
MUTATION COMBOS
Start small, then let the chaos grow:- Begin with a single bullet.

It's fun! The game is fun. I don't even really like survivor-type games all that much but this is a decently unique spin on the genre. The game is tough and easy to jump in and out of.3 found this helpful
I got #1 on the Hard leaderboard so I felt like I should write a review. This game is quite satisfying. Runs are quick and upgrades often feel quite substantial. Enemies pop in a satisfying way and the way upgrades help you kill things faster and better gives a constant stream of dopamine. Graphics are nothing to write home about, but not ugly and things are clear enough. The movement system is interesting, I've never seen another game use Flappy Bird's controls without being a straight rip-off, so kudos for that. My biggest complaint is just that every good run is basically the same. The key is just to get as many projectiles on screen as you can. There really is only one winning strategy. Multishot and split and attack speed are high priority. Take some chain and a level in explode for AoE clear. Take wall bounce or wall wrap and just sit at the bottom of the screen without bothering with the flappy bird mechanics. Homing is a trap if you want a high score, the area coverage from your bullet pattern is better. The biggest limiting factor for runs is how many hits you can do on the bullet sponge enemies, and only half to a third of the possible upgrades contribute to that, so it…1 found this helpful
THE KULKA is a minimalist arcade roguelite developed and published by Airem that demonstrates how a simple concept can evolve into an engaging and surprisingly deep gameplay experience. At its core, the game strips the bullet-hell survival formula down to its bare essentials, challenging players to survive inside a glowing digital arena while controlling a small floating orb. The most unusual aspect of the design is its control scheme—players interact with the entire game using only a single button. This decision transforms what could have been a traditional shooter into a rhythmic survival challenge where careful timing and positioning become the keys to staying alive. Rather than overwhelming players with complex controls or menus, THE KULKA focuses on pure mechanical mastery and fast-paced decision-making. The basic gameplay loop revolves around surviving waves of enemies that continuously appear within a neon-lit arena. The player’s orb automatically fires a projectile toward enemies, leaving the player responsible only for vertical movement. Pressing the button causes the orb to bounce or “flap,” allowing it to maneuver through enemy formations and avoid incoming projectiles.…1 found this helpful
