Thank you for your comment. And for organizing the Jam. :)
I had the idea to buy card effects with the coins we collected, but in the last hour I thought I couldn't balance it. Thank you for your comment.
You only get the effect of the cards when you click on them. I didn't fix the problems because I left it to the last moment. Thank you for your comment.
Thank you for your advice. I realized it wasn't very good. There was an hour left in the jam. I couldn't think of a better idea at the time.
You are right I shouldn't have used action.released. Thank you for your comment :)
