Bumper.io

Bumper.io throws you into a chaotic multiplayer arena where you control a bouncy ball competing against players from around the world. Charge into opponents to destroy them and collect gems scattered across the battlefield to boost your level and size. The key is timing — release your charge at the perfect moment to slam into weaker enemies, but beware of larger balls that can devour you in return. Every encounter is a calculated risk between aggressive pursuit and strategic retreat in this explosive io-style battle.
