Press E to swap between demo and edit mode. Edit Mode: - Click once to start a line and click again to end it. - Press space to cancel a line. - Press and hold space, then click on a line to delete it. Demo Mode: - Click and hold to drop balls at the mouse. NOTE: Bounce represents how much energy is conserved when a ball hits a line. When bounce is 1, the ball preserves its energy completely (which is unrealistic and can be glitchy).
