- Sound effects are feedback, not decoration. Play with the volume up at least until you know the game.
- Full-screen mode makes a real difference to precision. Use the button beneath the game.
- Set a small goal per session — one level, one upgrade, one new best — and stop when you hit it. It keeps the game fun.
