This was one of the best games I've played so far! A couple of things:
I think there may be a bug in the tutorial (or I'm missing something) as I got stuck but when I came back and read other comments I played the game and it worked fine.
The art and concept of each card is so cool and thought out, I kind of wish it was slower paced so I could have the time to really look at and understand what each card is/does. (I know that's tough given the theme).
Well done!!!
