Summary: It's not what I really expected from a Yoshi game. i know that this was back when the DS first came out and they were showing people how awesome the stylus system was, but this game seems very limited to me. You have the option of 2-3 games at first and more unlock as you get higher scores.
Summary: This game was pretty solid. Being one of my earliest DS games, I appreciated the creative use of the touch screen and ingenuity in regards to the dual screen interface. I had not played a lot of Yoshi's Island before playing Touch & Go, but it's apparent that the gameplay is mostly derived from that title. If you can pick this game up for cheap it's definitely worth picking up.
Summary: While essentially a fun collection of variants of the same minigame, Yoshi fans are better off purchasing Yoshi's Island DS, Yoshi's Island, Yoshi's Story, or waiting for Yoshi's New Island on the 3DS.
