The Flip Cube is another cube in the next update (0.9a) we are going to add that will flip from time to time.
One gotcha with this cube was that we were using a collision that extended into the padding outside of the cubes, so the ball wouldn’t hop around when you move across cubes.
The problem is that we don’t want the empty space to be collidable.
So we created a collision that fits the mesh snuggly, then switch between them when the cube flips and goes back to normal.
