Yeah. I really struggled with time management this year. Spent a little bit too much time on brainstorming ideas and once I finally settle for this game, I ran into a lot of weird bugs midway through development and barely ended up finishing the game at all. Did not even have the time to think about polishing anything! ^^' Will likely continue to work on this post-jam though... Glad you liked the concept!
Gold was added only one hour before the deadline. Thus the implementation is really barebones: each card has a 20% chance to contain gold, no matter the layout, thus including tiles without no walls. So technically not really a bug - but still pretty pointless, yes.
