The Author Comments should include the fact that if you tap the E key, the POV changes. I found that out quite by chance when I used the ancient wasd method, and my shaky hand hit E instead of D.
Apart from that omission, this is a great game. The graphics are clean, and I love the 3-D puzzle/strategy/skill combination. I'm pretty sure that my slight tremor made it harder for me than it might otherwise be, but at least I have good pattern recognition and general timing skills. Playing this while I'm drinking coffee is one heckuva challenge.
Nice work, but consider adding more keystroke info to your Author Comments. Do, and I'll change my rating to five full stars, because this game deserves it.
