About this game
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; gr…
