Yoshi Topsy-Turvy (known as Yoshi's Universal Gravitation in Europe and Australia, and Yoshi no Banyuu Inryoku in Japan) is a game for the Game Boy Advance that uses tilt sensitive controls, along with the standard d-pad and buttons. The game uses similar technology to WarioWare: Twisted! and Kirby Tilt 'n' Tumble. The game was poorly received by critics.
In Yoshi Topsy-Turvy, the player is required to complete the objective given to him or her. The spirit will first list the requirements and then subsequently the player will send Yoshi throughout the stage in an attempt to complete the level. In some stages Yoshi will transform into various objects (as he did in Super Mario World 2: Yoshi's Island). The entire world can be tilted left and right by tilting the Game Boy Advance (the game can also be played with a Game Boy Advance SP, Game Boy Micro, Nintendo DS, DS Lite, and Game Boy Player). This will cause various things to happen in the game, and is ultimately required to get through the stage.
