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.

At first it’s just you, one bullet and a handful of enemies. A few levels later the screen is full of bouncing, splitting, homing, exploding shots – and you’re trying to squeeze through the chaos with a single button.

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.

• Pick Split Shot – now you fire two bullets.

• Add Ricochet and Pierce – your shots bounce, pass through enemies and cover huge parts of the screen.

• Combine Homing , Explosive Bullets , Chain Lightning or Nova Blast to create your own broken combo.

Example mixes:

• Faster Shots + Multishot + Faster Bullets = Bullet Spam

• Multishot + Area Size + Bigger Projectiles = Wide Wall

• Multishot + Pierce = Line Killer

• Multishot + Ricochet = Bouncing Storm

• Shield + Time Warp = Slow Bubble

• Shield + Orbital Drone = Safe Core

• Freeze + Vortex = Frozen Vortex

• Poison + Vortex = Poison Zone

THE KULKA is all about making this one run as wild as possible – a quick neon arcade fix when you just want to flap, mutate and survive a little bit longer, with enough progression and competition to keep you coming back.
