* SugarWiki/AwesomeMusic: The theme used for the gurney ride in ''The Mad Doctor'' (reused as the final boss theme).
* BreatherLevel: ''Moose Hunters'' is significantly easier than ''the Mad Doctor'' or ''Lonesome Ghosts''.
* DemonicSpiders: The Weasels in ''the Prince and the Pauper'', most definitely. They take several hits, are difficult to beat if you run out of marbles, and can hit you from far away. [[Film/WhoFramedRogerRabbit Too bad you can't just make them laugh themselves to death.]]
* EnsembleDarkHorse: Just like his original short, the Mad Doctor (or rather, [[IAmNotShazam Dr. XXX]] in the original short) is remembered quite fondly in particular. Helped out by the fact that the cartoon and character is by far and large the most obscure cartoon in the game.
* GeniusProgramming: The Sega Genesis version of the game features Mode 7-style perspective effects in a number of the levels... produced entirely in software, as unlike the SNES, that system has no hardware support for such effects. In fact, the SNES version even ''lacks'' one of these levels.
* HilariousInHindsight:
** A video game featuring a FunnyAnimal star of a LongRunner franchise going through places he's been to before and allying with his past self or selves. [[VideoGame/SonicGenerations Remind you of anything?]]
** Right before the boss fight against the Mad Doctor begins, he removes a black cloak that makes him resemble the Phantom Blot, Mickey's lesser-known archnemesis from the ComicBook/MickeyMouseComicUniverse. The VideoGame/EpicMickey game would later feature the Mad Doctor and a revamped version of the Phantom Blot called the Shadow Blot as the main antagonists.
* MostAnnoyingSound: When Mickey is hit, he will say either "Ow!" or "Uh-oh!". Considering how [[NintendoHard difficult]] the game is, these phrases quickly become ''very'' annoying, especially the latter.
* {{Narm}}: In the Playstation version of the game, Mickey will for some reason ''always'' enter an animation that has him checking his watch when he finds Pluto at the end of ''the Mad Doctor'' stage, making him seem completely uninterested in having found his pet.
* PortingDisaster: Well not so much a "disaster" as it's just clear the game was possibly made more with the Sega Genesis/Mega Drive in mind rather than the SNES, as the SNES version has noticeable omissions compared to the Genesis/MD version. Level 5.5 is absent in the SNES port, some graphical effects like the film reel effect in the first level is missing, a segment of the Mad Doctor level is gone, one of the Mode-7 stages is gone (odd given Mode-7 was one of the SNES' big graphical features), there are less Mickey sound bites, but most noticable of all there are actually mid-level load screens in SNES port, which is odd given the game runs off a cartridge. One area some might consider superior are the sound effects and music, but that usually depends on who is asked. While still a well remembered port for those who played it on SNES, and far from a terrible one, it's still clear the developers made the game more with the SNES' rival in mind (and likely why Traveler's Tales future Disney games had the SNES ports handled by other teams).
* PolishedPort: The CD versions of the game feature high quality CD music by composer Michael Giacchino, even more Mickey Mouse voice clips provided by then-current Mickey voice actor Wayne Allwine, and extended versions of levels like the Mad Doctor stage. However the PS1 version also features higher quality graphics compared to the Sega CD version, with all the sprites having been redrawn, and a new chase sequence added to the end of the Mickey and the Beanstalk stage featuring Willie the Giant. The only problems some might have with the PS1 port was it was made even harder than the other versions, and both the original retail release and the PSN release suffer from NoExportForYou, having only been released in PAL regions.
* TheyWastedAPerfectlyGoodPlot: A minor example. It's a great game and a good 65th anniversary tribute to Mickey, but one wonders why there was no level devoted to the "Sorcerer's Apprentice" from Disney/{{Fantasia}}. That's one of Mickey's most iconic moments.
** Perhaps because that was a segment from a Franchise/DisneyAnimatedCanon compilation film and not a proper standalone Mickey Mouse short.
*** That and there was already a game featuring the Sorcerer's Apprentice aka the Fantasia Genesis game.
