A creative concept well executed, UI jank aside. Good art, good music choices. Variable clothing always makes for a good game system, though it tends to require a lot of art.
I'm usually a little scared off by card games because they look complicated, but this one was easy to understand and taught itself to me quickly. I do feel like sometimes I only won a round because the opponent decided to play the obviously wrong card, but there's a limit to how intelligent you can make the AI when you don't have many cards implemented yet (it would end up being you always lose or you always win), so this is fine for a proof-of-concept.
