I find the idea brilliant, but I seem to be too inexperienced to coordinate the three arms. I rated your game as if I would have had this experience. ;-) It's such a refreshing idea of an old concept. Perhaps it would be easier if you added controls: left arm - 7, 4, 1; down arm - 8, 5, 2; and right arm - 9, 6, 3. Just as an idea...
