The controls are all touch based. Tap and drag a shape at the top of the screen, and by using a second finger you can rotate the shape. I found it quite clumsy to rotate the shapes this way, and would rather have had some kind of rotate button option as well. Place the shape, and keep filling the void until you are done."
