Clever use of 3-D space for Go. I've seen chess and connect 4 with this concept - go is a very ambitious adaptation! I unfortunately don't know the rules for go, but figured them out a bit while playing. Managed to beat the AI with a smaller-size cube, Ending the game seems like it's missing some logic - no indication of who won, and need to fiddle with the play AI command/cube size or restart the game to play another round. I think the display could be made a bit more clear to read. On the larger cubes it can be tricky to track which depth level I'm interacting with after manipulating the cube.

Very interesting concept! I bet this would go over very well with fans of go!
