IGN DS

Preview, by Nix: "If Nintendo could slack off its self-imposed limit for touch-only play in this game just a bit, it would help some folks out, and might do a favor to the more hardcore as well so they have instant access to their eggs."

GameSpy DS

Review, by Phil Theobald: "The big problem with Touch & Go is that although it harkens back to some of the classic score-based games of the past, it also feels just as shallow as some of the classics." [Score: 3.5 out of 5]
