Shadow pong

Shadow Pong is a mobile game about keeping an invisible ball alive.

The phone is the paddle. The screen is the table. A virtual ball bounces in the space above it — you never see the ball itself, only its shadow. A blurry circle when the ball is high. Sharp and small when it's about to land.

Jerk the phone upward to bounce it. Tilt to control where it goes. Let it drift off screen and it's gone.

That's the whole game.
