The art is super good and the concept is very cool! The card placing mechanics were a bit frustrating, I wish cards would "lock" into positions on the board when you hover a card close to a position so you know where it's going to be placed, and that you can see potential card positions on the board.
Many times I would accidentally till over another card and get it stuck or accidentally pick up a card when I didn't mean to and now I have to play it's cost to put it down.
