The game looks really good and I see a lot of potential here! The hp description is something I catched after few rounds - it was not intuitive that avoidance is not enough. I had a huge problem with frame rate in browser, it's a shame that you didn't uploaded binaries to run. Maybe it would be better if you could select mages separately, not only switching left and right? Current mechanics for sure gives more challenge if that was your intention. I like the bass line when you fail. Nice job!
