Evolution Roulette

Every mutation makes you stronger. Some make survival stranger.

Evolution Roulette is a top-down arena survival roguelite where you evolve a small creature into an increasingly unusual fighting machine. Your attacks fire automatically—focus on movement, dodge incoming threats, and decide how much risk your next upgrade is worth.

Play it SAFE—or spin ROULETTE.

Choose one of two known positive mutations, or gamble on a powerful upgrade, a benefit with a drawback, or a survivable curse. Every mutation changes both your abilities and your appearance.

Roulette starts with 50% powerful upgrades, 35% mixed mutations, and 15% curses. Each spin raises Instability, bringing hazards, elite threats, and tougher enemies. How far will you push your luck?

• 18 mutations: grow fangs, sprout extra eyes, strap on rocket legs, and discover combat synergies.
• Two modes: conquer ten waves and defeat The Unstable One, or face recurring bosses in Endless.
• Move to survive: read attack warnings, weave through enemies, and time your dodge.
• Build, fall, evolve again: chase your best score with a different creature each run.

Controls

Move with WASD / arrow keys and dodge with Space. On touchscreens, use the on-screen joystick and Dodge button. Attacking is automatic.
