I'm not going to lie, I love Disney and I love Mickey Mouse. This review will be about as subjective as my mind will let it. Mickey Mouse is a big part of my life and with this game, I believe they made a third 16-bit masterpiece out of Mickey. The graphics are just incredible. I mean really, this is one of the best 16-bit games period when it comes to the quality of the sprites. Wow. The music is fantastic, being a person that decided on the Sega-CD version, Mickey Mania sounds just how I imagined Mickey's world(s) to.
Controls are solid, although the hit detection is a bit strange. It isn't problematic as you get better with every death, kind of like old-school Castlevania, however sometimes it just feels a bit cheap, like the Skeletons in the Mad-Doctor level. Wow those are hard. However with the right amount of dedication to the game these become manageable.
And I think that's the word of the review for this game: dedication. You are going to have to dedicate some serious time to progress through the game because honestly, despite it being a game (I imagine) released for kids, it's one of the hardest games for the Sega Genesis. It's one of the hardest games worth roughing through, however, because this game is one of the best Sega Genesis titles. 'Cept that ending... that sucked.
