Land of Illusion Starring Mickey Mouse, known in Japan as Mickey Mouse's Magical Crystal (ミッキーマウスの魔法のクリスタル, Mikkī Mausu no Mahō no Kurisutaru), is a platform game released by Sega for the Sega Master System in 1992 and Sega Game Gear in 1993. It is a sequel to Castle of Illusion Starring Mickey Mouse, which was also released for Sega Mega Drive/Genesis.

Land of Illusion is a typical platform game, with the player sidescrolling his way through 14 stages, trying to retrieve the crystal to the villagers. Mickey can attack his enemies by picking up an item (such as a stone block) and throwing it at his enemies, or he can jump at them in a sitting pose.

Throughout the game, the player can pick up items that imbue Mickey with new abilities, such as a rope for climbing up walls or a potion that can make Mickey shrink in size. Furthermore, the player can then return to previous levels and utilise these items to gain access to previously inaccessible areas.

Mickey begins the game with two power stars indicating how many hits he can take by enemies. Power stars can be collected throughout the game to give Mickey more health to a maximum of 5. However there is one power star on every level making 14 in total. Each star collected after collecting 5 gives you full health and an extra life. Most of them are in the inaccessible areas which require many of the special items collected throughout the game. Upon completion of the game, the number of stars the player collects is tallied. Collecting all 14 stars gives a special score bonus.
