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. Features Momentum-driven physics that reward feel over twitch reflexes 9 hand-crafted biomes, each with its own hazard and twist 12 abilities to unlock and combine Three difficulty modes, each with its own leaderboard Full controller support, remappable keys, and colourblind-friendly cues
