I’m not usually into deckbuilding roguelike games, but I thought this was a great submission for this jam! The UI/music/visuals are really well made. I thought it was a bit too easy to cheese, but it’s not as if there was much time to dedicate to balancing. I also think this really would have benefitted from some more tutorialization, since as someone unfamiliar with the genre it took me a bit to get into it.
Seems like a great foundation for further development though, hope you stick with it. Well done!
