The Great Circus Mystery Starring Mickey & Minnie is a platform game released for the Super Nintendo. It features simultaneous co-op gameplay, allowing players to control Mickey and Minnie as they traverse various levels. Players can acquire different costumes, each offering unique abilities such as enemy capture and wall climbing. Costume upgrades are available in-game, enhancing gameplay options. The game diverges from its Sega Genesis counterpart with minor visual updates to certain bosses and additional level content.
The game ditches the alternating two-player method in favor of simultaneous co-op. Another new feature is a password back-up.
Both Mickey and Minnie are identical gameplay-wise, and the costumes they receive don't differ from each other in any aspect except aesthetically.
The costumes include a sweeper, which can suck enemies and turn them into coins, a safari suit that can climb walls and swing from hooks and a cowboy suit that shoots corks and maneuvers by bouncing. The latter two outfits can be upgraded at a shop.
The Genesis version of the game includes a cosmetic change for the stage 5 boss and an extra room in stage 3.
