There are several control schemes available, and each is fully explained in game. If you use a keyboard control scheme, the left arrow and the 'a' button will move you left while the right arrow and the 'd' button will move you right. Up, 'w', or space will power up a jump. Using mouse controls, move the mouse left and right and Jumpcat will move to that position. Click to jump. To pause, press 'p'. You can play this on your Wii browser – just select the mouse option and use the A button on the Wii remote to click.
