It seems like a great idea, and the art is AMAZING, but I just can't figure the mechanics out. I think too many runes were introduced on the second enemy and I can't even figure out how to damage it. I also think it's a bit hard to understand what the rune is just by it's art, maybe if a popup text would appear above them when you move your cursor over them saying "fire" or "water" would help. But I do like the concept and think it could be a great game if the runes and mechanics were introduced more slowly.
