Gameplay consists of guiding a four-legged creature known as “Doodler” up an unending series of platforms without falling in an attempt to gain a high score. The character is controlled by tilting the gaming device in the desired direction. The greater the angle, the greater speed. In the BlackBerry version, direction of the Doodler is determined by tapping in the desired direction.
