Great concept, one of the most innovative for sure in my book.
My only real feedback, other than the lack of sound, is that It's hard to tell what's really happening in fight relative to all your stats. Some animations or damage numbers or timers etc would go a long way I think. Increasing the enemies health and reducing their damage might also work, as currently you can stack purely attack and kill everyone without ever taking damage, at least as far as I could see.
Great work!
