MUTATE YOUR BULLET. FLAP, EVOLVE, SURVIVE.
THE KULKA is a one-button bullet-heaven arcade game where your single shot evolves into chaos. Inspired by Flappy Birds, Vampire Survivor and Pattern Survivors: Bullet Hell.

- Upgrade system – stack crazy bullet mutations with every level-up.
- Fast-paced arcade chaos with endless replayability.
- Minimalist neon visuals that keep you focused.
Local high scores and instant restart loop.

3. Add Ricochet and Pierce — chaos unlocked.

There is new a version THE KULKA 1.5.7 (web and bulid, gamepad support, fixes, new mode FLOW, keyboard control ARROWS + SPACE and more) and Steam version: https://store.steampowered.com/app/4221950/THE_KULKA/
I added a new update:
Added new difficulty levels, available from the Options menu or before starting the game (later an option will appear to disable the pre-game window).
New upgrades, e.g., faster XP gain.
Slightly adjusted level balance.
Added separate leaderboards for each difficulty level.
Updated localization (around 200 translations).
Other minor bug fixes.
Updated the browser version (Chrome, Firefox, MS-Edge).
Splendid! Only played briefly and a bit confused, but seems like a really good game. Definitely interesting and creative! Need a bit of practice. Oh, works fine on a smartphone, unlike many browser games.
@PatchSO1967 Thank You. You start with one bullet, collect XP, and pick mutations (Split, Ricochet, Explosive etc.). After 2–3 upgrades it clicks together (mix). Glad it runs well on phone.
PS. An update will be coming soon that will add a difficulty level.
I added a new update (new difficulty levels relax/training etc.)
