This is a really solid jam submission! The controls are very fun. I'm not sure if you made the art and music, but they fit together really nicely and the art style is perfect for this game. The screen shake is cool! A few things I noticed: The music doesn't loop, which is unfortunate. I picked an explosion card and I think it flung me from the arena, because I got softlocked out of the game after that and the restart button didn't seem to work. Other than that, this is a very polished jam submission and I'm pretty impressed, especially since you say it's the wrong version. Good luck, happy jamming!
