How to play
Touch your pen, drag back like a slingshot, and let go to flick it.
Pull further for more power. Drag back to the start to cancel.
Flick near the end of the pen to make it spin. Flick the middle to push it straight.
Knock the other pen off the bench, and keep yours on it.
If your own pen falls, you lose the round. If both fall, the round is replayed.
