The game is controlled via Wii Remote for choosing options in the game menu (the A is important to use after ending a level to go to another and to confirm at options and a 2 button is important to go back in the game menu while choosing options) and a Nunchuk for moving a guy named simply "Dude" (Hepburn: Di Ud) in his ball. The goal is to move the ball until a red coin with an arrow, which its signature is the level goal.
The game is controlled with a body. The human body gets his arms up and ball will roll properly. Without hands on hips when a human bends to the right, the ball will go right, when bending to left, the ball will go left.
3DS (Available on Virtual Console)
The game is controlled like this: The D-pad serves as the ball movement, the A button for confirming options (while in game menu) and B for going back (while in game menu).
Wii U (Nintendo eShop)
Same as 3DS', but only instead of D-pad the ball is controlled via an analog stick.
