Ten throws per world. Flick the paper, read the wind, sink it. Four makes earns a star and opens the next room.
Swipe up from the ball. Faster flicks throw farther; the angle of your swipe aims.
Wind pushes the paper sideways. Aim into it. Some bins move.
4, 6 and 8 makes. A swish that misses the rim scores +5.
Each world bends the arc a different way. Earn one star to unlock the next.
