All controls of the game, including aiming, power selection and movement, are specifically designed for touch-screen devices. Movement is directed by the iOS device's accelerometer: the player maneuvers the character in the combat zones by tilting the device. The accelerometer automatically recalibrates at the beginning of each combat zone. In order to give commands to Jacob, the player has the ability to pause the action via the power wheel on the left side of the screen. Resuming combat also recalibrates the accelerometer.
