Poachers have captured Barney the kangaroo in the Australian outback, and they have packed him in a crate. Luckily, the crate falls out of the plane soon after takeoff, and Barney lands safely. The game begins with Barney's trek back home. Players control his speed and hopping distance by tilting their iDevice forward and backward, while control of movement left and right is accomplished by tilting the device appropriately. Players can calibrate device "level" at the start of each game.
