A neat game so far! I really enjoyed the overall concept - very fun. It crashed at one point (I pasted the error message below in case its useful) and I think the resolution was slightly dodgy because It was too tall for me to see the health bars or some of the spell names... And there didnt seem to be a way to quit. But from a gameplay point of view, very good! I'd love to play a more polished version.
