For all of it's innovation, and personality, Touch & Go feels incomplete. It seems like Nintendo had a bunch of great ideas for parts of a game, put them together, polished them up, and then forgot to connect them into a cohesive whole. Yoshi's Island was an amazing game, and Touch & Go feels more like a quick survey of its predecessor rather than a full-fledged sequel. It sits uncomfortably on the borderline between puzzle game and platformer, but it lacks the substance of the latter while failing to capture the "zen trance" feel of something like Tetris or Lumines. It's an incredibly fun game, and its obvious ties to one of the greatest 16-bit platformers of all time will warm the heart of anyone with good taste. With a little more variety and a bit of effort to bring the whole thing together, Nintendo could have had another classic on its hands; as it stands, Touch & Go is just another high-quality novelty for the DS.
