Great work on a card game in such a short amount of time.
Music is pleasant.
The controls tab in the menu helped me get going quickly. Controls felt very intuitive, clicking on a card to see it's description.
I liked the card animations and shake.
The AI felt engaging to play against- I lost the first time.
Having two decks where you have to balance resources fit the theme very well. I found myself focusing on managing corruption and ignoring the soul points mostly, since there's always an abundance of them. I was top-decking from destruction most of the time.
