Sonic Labyrinth

Sonic Labyrinth is a puzzle/platformer for the Sega Game Gear. Sonic must move around a pinball-like arena, using his power to roll into a ball to defeat badniks and pick up keys in order to exit throught the GOAL door and clear the stage. The only move Sonic can use in the game is the spin dash, because Doctor Ivo Robotnik (Doctor Eggman in the Japanese version) secretly replaced his famous red shoes with another pair that took away his ability to run fast or jump.
