While you're on the Canabalt HD menu, try making a swipe gesture on the touchpad of the OUYA controller. You will notice that a cursor appears; you can use this cursor to navigate menus. The touchpad can also be used as a secondary jump button while in the game. This functionality is pretty straightforward, but the creative applications of the touchpad are limitless. You could program a sword to slash with a swipe of the touch screen, let a player design custom decals by drawing them with their finger, or use touch input to calculate the direction and velocity of a cannon shot.
