Sega's Game Gear version of Castle Of Illusion Starring Mickey Mouse , based on the Disney platformer, features a similar storyline where Mickey must rescue his girlfriend Minnie from the evil witch Mizrabel. The main objective is to collect the gems of the rainbow across six unique levels, including a magical forest, toy land, and candy world.
Gameplay involves navigating through each level, avoiding obstacles and enemies while collecting gems and power-ups. Enemies can be defeated by jumping on top or using objects picked up around the environment to attack them. Mickey's ability to carry objects also enables puzzle-solving, such as placing objects in specific spots to access new areas. Some levels require collecting keys to unlock doors, and treasure chests offer hidden contents like extra lives, health boosts, or coins for points.
