Use the [Arrow keys] to move the 'pusher' around. [Spacebar] resets the level. If you're facing the right direction you can trap the ball and move it, or you can simply push it along using a side. Move the ball to the exit block to win the level. Levels are wrap around for the 'pusher' if there are no obstacles but the ball cannot be taken along. Levels loaded from xml files, easily extensible.
