Materia: Glass Marbles & Water

Tilt your phone and glass marbles roll, click against the walls, and tap back into your hand. Press one and it follows your finger. Touch the water and it ripples. Every hit is heard and felt at the same moment.

Glass Marbles: four marbles roll, collide, and click against the walls. Press one with your fingertip and it follows your finger. Water: tip the phone and it sloshes. Touch the surface and it ripples with a small drip.

There is nothing to win and nothing to get wrong. The same motion gets the same response, every time.
