Meh.
Good idea, but the mechanics of the game are awful. It goes much too fast from the start, and the character/shield select is utterly pointless, because as far as I can tell they change nothing about the game itself.
Having to click to reflect the spells- and especially the cooldown time on that- is annoying as hell.
Lastly, there's not even any sort of description of what "Last Stand" or "Shield Wall" do. A note on that would be nice.
