Drag on the cloth to aim — the line follows your finger and shows where the
cue ball first makes contact. Then press the Pull rail on the right and drag
down: the cue draws back, and letting go plays the shot. Slide back to the top to
think again. After a foul, drag the cue ball itself to place it.
Keys: ←→ aim, hold Space to power up and release to shoot,
