A little bit confused at first, but I think I got the hang of it after dying a couple of times; card games can be a bit tricky to teach in the short timespan of a game jam play session.
Visually, the game looks great. I love the Baltro "gameyness" of interacting with the cards. There weren't all to many SFX, but the ones that were present (the damaging a card sound) fit well within the game. Also, the music was quite nice; it set a good atmosphere for a playful card game.
Neat idea for the theme. Cool submission.
