I gave it a try. Got stuck on the second tutorial level.
Also, the control mappings are pretty terrible. My keyboard is split down the middle, leaving B no where near HYUNL/JK
Even so, you need to do something about them; the south-easternly directions don't match their north-west counter parts.
Like, bwuh? Why is "move right" way the frak over there? I'd go with HUIKMN with JL for rotation.
