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.

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.
