How to play
Rotate the disc with one finger or the arrow keys. Gravity pulls the ball downwards; optional tilt control lets you steer it with your phone or tablet. Reach the emerald, sapphire and amethyst sockets in order, then the golden centre. Each socket opens its matching gate. Choose any of the eleven levels in Settings. Jump gives the ball a short impulse against gravity. All opened gates are freely passable; Jump is optional in every level. Solid walls and locked gates cannot be jumped. Strength ranges from 50% to 1000%. Ball Size 5 is the default in every level; you can choose a smaller ball.
Keyboard: left/right arrows rotate the disc; Space pauses the game. J: small hop.
