About This Game

Tumly is a 2.5D physics survival game about a humble rolling ball and a very long way down.
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 trade
momentum 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 tied
to 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.
  

Each mode keeps its own leaderboard, so there's always a score to chase.
