Guide Tumly across drifting, bouncing platforms, ride your momentum instead of fighting it, and
survive one treacherous biome after another — because the only real rule is: don't fall.
Keep rolling
Tumly can't fly and can't stop on a dime — it rolls. Platforms float, collide, and trademomentum like billiard balls, and you're just a passenger learning to steer. Read the physics, time
your moves, and carve a clean line through the chaos.
Earn your belts
Your lives are judo belts, ranked white to black. Climb the ranks and Tumly unlocks new powers tiedto each belt — jump, reverse gravity, freeze the platforms, float, and more. Pop collectible bubbles
for passive perks like a shield, a battery, or extra grip. Fall in, and — depending on your
difficulty — a belt is the price.
Nine biomes, nine ways to fall
- Green Pastures — where every roll begins.
- Desert Dunes — crumbling sand platforms over hungry quicksand.
- Frozen Wastes — shearing ice, freezing water, and a chilling slowdown.
- Lava Fields — melting ledges and walls of fire.
- Dark Forest — ghostly platforms and a forest floor that hides a pit.
- Monopole Match — magnetic platforms you must steer to a single colour.
- Crystal Caverns — fracturing crystal that shatters if you linger, on ice-slick footing.
- Power Pool — roaming lightning in a charged arena.
- Cloud Heaven — wind-blown clouds and the final climb to the sky.
Three ways to play
- Gold — the full challenge. Every death costs a belt; run out and it's game over.
- Silver — belts only rise, never fall. Climb without the sting.
- Bronze — start as a black belt with every ability unlocked. Pure, relaxed rolling.
