KEYBOARD: Tap the arrow keys or WASD to move. [Space] to absorb, change, mix or store circle colours. [R] to reset. [M] to toggle music. TOUCH-SCREEN: Press relative to the player where you want to move. Tap on the player to use different circles. Press and hold on the player to reset. You are a circle. Your goal is to reach the square on all 17 levels. The instructions are explained in-game. Collect colours and mix or alter them when in colour storages (double circles) or inverters (thick circles). Colour gates (diamonds) restrict access to colours other than their own.
