Yeah, I was out of time to fix the bugs by the time I submitted it to the jam, but I'm glad they didn't take away from the experience too much! I was hoping that would be the case, since the bugs only start happening when you start a new run.
I thought it would be a cool visual for the cost of the card to be visible when you hover over the card, but thank you for the feedback! If I ever come back to this game, or try to create another card game similar to it, I'll definitely keep that in mind! Thank you for playing, and thank you for your feedback!
