* SugarWiki/AwesomeMusic: Any of the remixes that were put into the game, and Galaxy's Floater Land Theme.
* GameBreaker: Unfortunately for the designer, there is obviously no way to ensure an entirely linear way of game progression, since certain areas can actually be accessed prior to their storyline appearance.
** Hover FLUDD. Lose your balance on a platform? No problem! [[DiscOneNuke Unless the platform moves in such a way you can't hover back to land, as they are wont to do later in the game.]]
* MostAnnoyingSound: Without an awesome sound card, the bursts of static from too many simultaneous sounds, most notably Mario's walking sound effect. KCHKSH! KCHKSH! KCHKSH! KCHKSH! KCHKSH! KCHKSH! KCHKSH! [[OverlyLongGag KCHKSH! KCHKSH! KCHKSH! KCHKSH! KCHKSH!]]
* ThatOneLevel:
** [[BrutalBonusLevel The Edge of the Mushroom Kingdom.]] This game makes you ''earn'' your HundredPercentCompletion.
** Playing some of the later levels (such as Lethal Lava Land and Tick Tock Clock) can be a big pain in the butt without Hover FLUDD.
** [[spoiler:Also, the CollapsingLair segment of Bowser's Castle after Bowser is defeated. The area's ''covered'' with fire and spinning platforms, and FLUDD is not able to be used whatsoever.]]
