Description taken from Nintendo DS version of this game

After resounding success on Game Boy Advance and a worthy follow-up on GameCube, Nintendo's tongue-in-cheek "WarioWare" brand of fast-paced mini-games comes to the dual-screen handheld with this release. WarioWare: Touched! was designed from the start to make use of the handheld's unique features, so while veterans of the series may recognize the frantic pace and satirical style of the game's numerous five-second challenges, they may need to rub the touch screen, blow into the microphone, or interact in other unusual ways in order to beat them. In fact, each of the 180 "MicroGame$" featured in Touched! can be played without using the traditional action buttons at all. ~ T.J. Deci, All Game Guide
