Super Onion Boy

Super Onion Boy is a retro platform game where you rescue a princess trapped in a magic bubble by a terrible monster. Battle enemies, dodge obstacles, and face a final boss.

Use arrow keys to move, Z to jump, and X to fire at enemies on desktop. On mobile, touch controls handle movement and actions, and press P to pause.

Defeat monsters on every stage, survive hazards, and beat the final boss to free the princess from the magic bubble. Clearing all levels completes the rescue mission.

Use ranged attacks with X when enemies crowd narrow platforms. Learn boss attack patterns before the final fight so you can dodge and strike safely.
