A very original premise, executed quite well. I really enjoyed figuring out how this unusual combat system works. Lovely graphics, nice epic music.
In the interest of constructive feedback, I have only a couple of minor suggestions:
1. The "END TURN" button appears to be unavailable when it is, in fact, available, just not highlighted. I found myself waiting and waiting before I figured this out! :)
2. The current game is not extremely challenging. Understandable, since it's too easy for jam games to fall into the trap of becoming too difficult (that definitely happened to mine).
