I really like the UI work and the art, especially the interact prompt and the card designs, they were both very cool looking. The attacks felt really solid and weighty, and the platforming was overall pretty tight. I also liked the enemies and their overall design and the amount of enemies you throw at the player at once is at times pretty crazy. I think more environmental art would have went a long way here in making the style hold together better but also in making navigating the levels a bit easier as landmarks would help in remembering paths and whatnot. I also agree that generally the card mechanic could have been better explained although I'm pretty sure I figured it out. The soundtrack was overall solid, I think they loop a bit too soon though.
