Pretty buggy. Often the UI wouldn't disappear when it should. And the game crashed after a fight.
Also, shouldn't you be able to see the card descriptions?
It looked interesting though.
Uh, after the first fight, a text box saying 'good luck' or something showed up and wouldn't disappear. That might have been your intention now that I think about it, but it looked like it bugged out when I played it. Also, the 'pick your rewards' menu showed up after a fight correctly, but then it appeared once again when I returned to the main map. I think the crash happened right there actually.
