That was epic, good job.
It was tense as hell near the end. The last enemy drew an attack with 3 damage and so did I (randomly with only 3 attacks / 6 cards), I only had 3 hearts and he only had 2. I was actually worried I'd get that far and lose.
This is a great game, well polished and the concept / theme implementation is fantastic - way better than my own submission. Can't praise it enough. I don't often play until the end of a game!
