BallPark 3DX

Imagine a square checkered board. Put on it balls on starting places that show a starting direction thanks to arrows on them. The goal of the game is easy: guide the balls to the exit. Simple, yes, but you will have to avoid spikes, you will encounter corners that change the direction and depending on the ball (i.e. plastic, metal), its behaviour won't be the same: for example, beware of magnets using a metal ball.
