Navigate around the screen with the arrow keys.
Press Space to pause.
Choose your colour and shape before you start a level.
Red beats yellow, beats blue, beats red.
When two pieces collide, the winning colour performs its action:
Circles take the other piece's colour, Squares explode the other piece and Triangles make the other piece disappear.
The aim is for your colour to gain the majority of pieces on the screen (if you're a circle, you change teams when you change colour).
