Castle of Illusion starring Mickey Mouse

Castle of Illusion Starring Mickey Mouse is a side-scrolling platformer game developed by Sega of America. It was released for the Sega Genesis/Mega Drive and also for the Game Gear. While the Game Gear version had redesigned levels, the mechanics of the game were still similar to the Sega Genesis/Mega Drive version.

In this game, players take control of Mickey Mouse and embark on an adventure to save Minnie Mouse from the wicked witch Mizrabel. When the game starts, you enter the witch's magical castle. Problem is, you can't reach the tower where the witch is located. So, you have to enter mystical worlds within the castle's secret doors to find gems. Each world holds a gem, and when you collect all of them, a rainbow bridge can be built which will allow you to enter the witch's tower, where the final battle takes place.

As Mickey Mouse travels through these wacky and dangerous worlds, he will have to defeat a variety of enemies to advance. To attack enemies, Mickey can stomp on them, or fling apples and marbles at them, which can be collected throughout the game. Mickey Mouse can also collect icons that restore health, add extra lives, or boost your score.

The game features three worlds various difficulty levels, on the easiest of these Mickey only completes the first world or each stage before advancing, (essentially making the game a three stage game) on the various other  difficulty settings however Mickey must complete upwards of 5 or so stages per world. The easiest difficulty level also eliminates all of the bosses from the game.
