Overall a very unique idea, will be very interested to see how this one turns out! The main tricky part to me sounds like the AI, and ensuring things are effectively turn-based, so a bit of scripting in your future I reckon. A bit more concept art beyond the youtube video would have been nice (there appears to be a broken image at the end, maybe that had something in it, but the main factor was that concept art was presented without caption or description).
