Cool concept and the art is lovely!
Since it is not finished I wont say so much about what doesn't work but instead congratulate you on the thing you worked most on, the cards. They look really nice, the drawing, and very "Slay the Spire" like using of them is very well polished. I enjoyed playing around with the targeting arrow and shuffling my cards around :)
