"World of Illusion Starring Mickey Mouse and Donald Duck is a 1992 platformer and the sequel to Castle of Illusion. In this game, Mickey and Donald get sucked into a magic box containing the world of illusion and while inside; they must traverse various Disney worlds to escape." - Alex Legard from Video Chums
Great game I own this and Castle of Illusions on SMS and Genesis other great Mickey Mouse games Epic Mickey and Mickey Mania. Trying to find Mickey Mania on PS1 is a pain in the ass I own it on SNES, Sega CD and Genesis.
