THE KULKA

One button. Infinite chaos. This brilliant bullet-heaven arcade game starts you with a single shot and evolves your firepower into an absolute screen-filling mayhem through upgrades and XP collection. Inspired by Flappy Bird's simple controls and Vampire Survivors' addictive progression, it creates something entirely unique.

One-Button Simplicity

Click or tap — that's all you need. The elegantly simple one-button control scheme means you're dodging bullets and enemies with just a single input, creating a beautiful contrast between the simplicity of the controls and the complexity of the chaos unfolding on screen.

Bullet Heaven Evolution

Watch your firepower evolve from a humble single shot into a spectacular bullet storm that fills the screen with projectiles. Each upgrade transforms your offensive capabilities, turning you from a vulnerable flapper into an unstoppable force of destruction that shreds everything in sight.

XP Gem Collection

Collect glowing XP gems dropped by destroyed enemies to fill your experience bar and level up. The gems scattered across the screen create constant micro-decisions about risk versus reward — do you fly into danger for that gem cluster or play it safe?

Upgrade Selection System

Choose from powerful upgrades each time you level up, shaping your build and play strategy on the fly. Each upgrade choice meaningfully changes how you play, creating unique runs where no two sessions feel the same thanks to different upgrade combinations.

Flappy-Style Dodge Mechanics

Navigate through waves of enemies and projectiles with flap-based movement that demands precise timing. The familiar flapping feel combined with bullet-hell intensity creates a uniquely challenging experience that's easy to understand but incredibly difficult to master.

Escalating Chaos

Survive as enemies become more numerous, more aggressive, and more varied over time. The screen gradually fills with more threats and more projectiles, testing your limits and creating those unforgettable clutch moments where you somehow weave through impossible-looking situations.

Roguelike Replayability

Every run offers different upgrade paths and enemy patterns, ensuring massive replay value. The combination of random upgrades and escalating difficulty means you'll always find new strategies to try and new personal bests to chase with each attempt.
