RollMorph is an endless side-scrolling platformer where your ball's size changes depending on what it rolls over. Lava platforms make you grow larger, ice platforms shrink you smaller, and normal platforms gradually restore you to your default size. Fall off the screen or hit an obstacle and the run ends.
Tap to jump over obstacles — spikes, walls, saws, and lasers scroll toward you as the speed increases. Collect power-ups: Shield blocks one obstacle hit, Magnet attracts nearby coins, Speed Boost increases your travel speed, Shrink temporarily reduces your size, and Coin gives instant coins. Unlock new ball skins with coins earned per run.
