Sonic Labyrinth

Sonic Labyrinth is a puzzle/platformer for the Sega Game Gear, released 17 November, 1995 in Japan and sometime during 1995 in the US and Europe. It is also playable on Sonic Adventure DX and in the PC, PlayStation 2 and Xbox editions of Sonic Mega Collection Plus. The game features isometric 3D gameplay similar to Sonic 3D. Sonic and Eggman are the only characters in this game.

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 through the GOAL door to clear the stage. The only move Sonic can use in the game is the Spin Dash, because Doctor Ivo Robotnik (Doctor Eggman in the new games) secretly replaced his famous red shoes with another pair; The Slow-Down Boots that took away his ability to run fast or jump,and they cannot be removed at all without the use of Chaos Emerald energy. Sonic does retain his ability to walk and Spin Dash, however there is a time limit in each stage so it is best to move quickly.
