@Super_Hippo, the sides are inexorably linked to the axes of cube rotations and, in changing that, the direction of rotation for at least one will change, making a big mess out of things.

@Super_Hippo, unfortunately it would be way to difficult to make that change -- and much more difficult to have it as an option. I would probably have to create a separate world and modify a bunch of data values. What is with "#HighscoreWaitingRoom"?

This is not intended to be a game. It is a demo that uses multiple support classes that can be re-used by those who may want to produce games having behaviors these support classes provide.
