The Game Boy Advance version of Monsters, Inc. is a platform adventure game where you play as Sulley, trying to reunite Boo with her door after it’s been destroyed by Randall. The game features multiple levels set in various locations from the movie, like the factory floor, the changing rooms, and the door vault. You’ll need to recover pieces of the door scattered across the levels and solve mini-puzzles to reassemble it. Sulley can use his roar to scare CDA agents and even has a “Laugh Launcher” to surprise enemies. The game also includes randomly generated levels, different difficulty settings, and minigames.
