The dimension-flipping mechanic received generally positive reviews. "Gamasutra" described the game as a "landmark Wii release" and a "hit with critics". The website noted that the game's dimension-flipping mechanic, puzzles, creativity, and writing received praise from critics and that most criticism was directed at its inability to please those looking for a pure RPG or platforming game. Its story also received praise, although some criticism was directed at the large amount of text. "Game Informer" reviewer Bryan Vore appreciated the inclusion of more platforming elements and the dimension flipping mechanic while praising the writing as "arguably the best" in any "Mario" RPG. Reviewers at "Famitsu" lauded its dimension-flipping mechanic, balance, and control scheme.
