Oh, I like the concept of forgetting abilities as the fight goes on. Nice UX and layout design, everything was very clearly readable (which, the more I struggle with UX, the more important I realize it is).
I think I would have liked to have been able to hover over abilities to see their stats, rather than having to click on them... also I didn't see how to see my own side's hit points except when it was their turn. I might have missed something, but alternatively it would have been nice to have health bars, or when you hovered the mouse over your own side you could see various hero's healths.
