Really good and fun game. Loved the music bump for the battle.
Unfortunately I had a game breaking bug in round 8 which caused the game to battle to freeze in the web version. Both charachters registered a charge action as their last, charged and remained in that state forever.
All in all I gave a stellar rating BUT:
If the theme were "slice" 5/5. For erase, to me that's a real stretch. if you could rub actions off the card maybe...
EDIT: one more thing - in round 6 or so i accidentaly discovered that one can move cards in the bottom row. This is not mentioned on the game site. Not sure if its mentioned in the tutorial. Anyway, I consider that playing "hard mode" :D
