World of Illusion Starring Mickey Mouse and Donald Duck[a] is a platform game developed and published by Sega for the Sega Genesis. The game released in December 1992, and is part of Sega’s Illusion series of Mickey Mouse games. Gameplay: Players can either play solo as either Mickey Mouse or Donald Duck, or co-operatively with two players controlling Mickey and Donald while sharing from the same pool of tries. Mickey and Donald can run, jump, or attack by flourishing their capes. Enemies defeated in this way turn into doves, cards, or other harmless objects depending on the enemy. After defeating the boss of each level, a new magic spell is learned, allowing the pair to traverse the next level; i.e. flying on a magic carpet or going underwater in an air bubble. The gameplay changes significantly depending on the characters chosen. For example, Mickey can squeeze through certain gaps, while Donald must find a different route, leading him to entirely different realms. When playing in two-player mode, the players can stand on each other’s shoulders and use ropes to help each other out, and Mickey can pull Donald through gaps his (evidently very stiff) tail feathers prevent him from fitting through.
