This seems like a really cool idea with lot of potential, good job!
Feedback:
I wish I could see enemies attack range, so I would know where not to move (this will really help to make your choices even more based on strategy and planning)
Also I found a bug on the end of the first level, when you are close to the stairs, you die for no reason (even if enemies are far away, seems like if something it's hitting you) Hope you can find out what it is!
