I like the twist on the classic card battler, and I think I would enjoy this style more compared to the classic card battler with some more polish. The characters are cute, and the game is fairly straight forward when you know what to do. The music is a little too repetitive, but overall a good entry for the period of the jam.
If you plan on working on the game post jam, it would be nice to see the same art and style as the splash image for everything in the game.
