World of Illusion Starring Mickey Mouse and Donald Duck

World of Illusion Starring Mickey Mouse and Donald Duck (released in Japan as I Love Mickey & Donald: Fushigi na Magic Box) is a 1992 platformer video game developed by Sega AM7 and produced by Sega for the Sega Genesis. The game was released in North America on December 17, 1992, in Japan on December 18, 1992 and in Europe on December 19, 1992. It is part of Sega's Illusion series of Mickey Mouse games.

Whilst preparing for a magical act, Mickey Mouse and Donald Duck discover a magical box. However, this turns out to belong to an evil magician (Pete) who sends Mickey and Donald to a magical world. Mickey and Donald must now work together in order to find a way back home.

Players can either play solo as either Mickey Mouse or Donald Duck, or co-operatively with two players controlling Mickey and Donald whilst sharing from the same pool of lives. 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.

World of Illusion comprises five principal stages named the 'Enchanted Forest', 'Among the Clouds', 'Underwater Adventure', 'The Library', and 'The Magic Box'. There also exist, within these five stages, three sets of sub-stages (some of which are optional) which are accessible only while playing either as Mickey or as Donald in one-player mode, or in two-player mode.

Candy restores a single health point. Cake restores all health points. Collecting 52 playing cards awards an extra life. The top hat awards an extra life. The silver playing card provides invincibility for a short period. The firework destroys all on-screen enemies.

The game's music, artwork and animation shows influences from classic Disney animated films (similar to the Kingdom Hearts series), including Snow White and the Seven Dwarfs, Pinocchio, Fantasia, Sleeping Beauty, The Sword in the Stone, and The Little Mermaid. Some of the influences are directly literal, such as the appearance of the playing-card soldiers from Disney's 1951 film adaptation of Alice in Wonderland, in the castle-garden section of the 'Magic Box' stage.
