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.

Cosmetic skins (including holiday themes) – full version only

In the full version of THE KULKA, you unlock additional cosmetic skins and visual variants (e.g. Christmas and New Year themes) that change the look of the game – with no impact on balance, mechanics, or leaderboards.

All skins are earned through challenges and objectives – no currency, no microtransaction grind.

Purely cosmetic. Zero advantage, just style.
