Pretty good entry. Love the main menu, but the cells/card art somewhat clashes with the rest of the game style.
As for gameplay, a lot more decision making is needed than at first appearance. Pretty fun.
If I had to say what I'd change with the game, probably the card selecting. Slightly annoying how it effectively blocks the game screen. It would be fine if it still came at fixed intervals but off to the side, or at the bottom or something, but having it come in and block the gameplay is a bit of a nuisance, considering the game doesn't pause meanwhile.
As a whole though, still amazing for a game jam entry!
