I'm coding up a version where the user enters the dimensions of an arbitrary hyperprism and plays in it. The controls are going to be obnoxious though, best idea I have so far is ab-cd for moves in small boxes, ef-gh for metaboxes, ij-kl for metametaboxes, etc.. I'm also trying to make a smart AI so I don't have to play said versions.
