From Nintendo: Players navigate the exotic locations in Wario's first platform game using the Nintendo DS buttons, but they use the touch screen to draw symbols on Wario to help him transform into his different disguises. Want to change into the laser-shooting Cosmic Wario? Draw a bubble helmet on his head. To change into Dragon Wario, just draw a long tail on him. Each of Wario's eight different disguises has different abilities to help him fight enemies and get past obstacles.
