This game is about trying to get a white ball (or square right now) into the big purple one. You have to fight gravity and friction with anti-gravity blocks.

You also want to get to the purple square with the shortest run, least amount of anti-gravity blocks, and fastest build time. Right now it only counts how many blocks you’ve placed, and how long it takes the ball to get to the purple one.
