An early preview of Castle of Illusion: Starring Mickey Mouse for the Sega Master System.
==Notes==
* This is the same prototype featured at the Summer Consumer Electronic Show of 1990 (which took place on June 2 to June 5th of the year).
* Non playable demo.
* Different title screen.
* While the HUD graphics are the same, the tiles used in the level that is shown is completely different to those used tiles used in the first Forest level in the final.
* A "Coming Soon" screen is displayed after the demo.
* There is no sound in the prototype.
* It's unlikely there's any data aside from what's shown because the size of this prototype is smaller than the size of the final game.
