One part later in the game, where Mickey grows to a tremendous size then shrinks to a minuscule size, was also replicated exactly as in the cartoon. The opening sequence also plays out similar to the beginning of the cartoon, even perfectly replicating Mickey's "walk through the mirror" animation (similarly, this would also be used in the intro sequence to Junction Point's Epic Mickey). This game's plot was based on " Thru the Mirror", a 1936 Mickey Mouse cartoon. But when Nintendo finally announced the product at the 2002 Electronic Entertainment Expo, This was proved that it was a completely different game, instead. After Mickey wakes up, he goes downstairs to get something to eat and a model of the ghost is shown hanging on the ceiling fan and the ghost's laughter is heard.Īt Nintendo's Space World 2001 show, where it was just beginning to show more Nintendo GameCube titles, A Disney title was announced which showed some screenshots of this game, which was assumed to be a platformer like much the vein of Disney's Magical Quest on the Super Nintendo. However, if the player doesn't find all the mirror pieces and has only found at least eight pieces, Mickey can still leave, but the ghost can't leave with him at all. If the player chooses to leave, Mickey says goodbye to the ghost and begins to go home, but the ghost decides to go with him. If the player chooses to stay, the ghost then runs off, leaving Mickey stuck in the alternate world until he renters the mirror room where the leave or stay process repeats. The player could either chose to stay or go. After repairing the mirror, he prepares to leave but the ghost stops him revealing that it only brought him here so he can have someone to play with. Whenever he finds a piece, it will fly back to the mirror and put itself back in place. The player must direct Mickey to outwit enemies and pull gags in order to get past enemies and the aforementioned ghost and recover the broken mirror pieces he needs to go home again and search for twelve magic stars and items needed to help him throughout his quest. Stuck in an alternate universe that strangely resembles his own house, Mickey yearns to get back through the mirror to his own house and his own bed. One night, a mischievous ghost traps a sleep-walking Mickey Mouse inside a magic mirror. Special souvenirs may be uncovered as well, which are displayed in Mickey's room at the end of the game, such as Pluto's collar or Minnie's bow. Mini-games, such as having Mickey fly an aeroplane or ski down a mountain, are available throughout the game.
At certain points, the player is able to have Mickey perform a special move that generally involves having him stomp on an on-screen enemy.
Mickey will react to what the player does and what he encounters in the game by expressing curiosity, getting mad, falling down, running away, standing his ground, or other actions. The game uses a simple point-and-click mechanic which involves using a cursor to guide Mickey Mouse to various locations.
