I had a fun time with the game. Managed to beat the boss and seems like it start over a new run don't know if the enemies attack/def are scaled here but managed to get to the boss again but died to him due to bleed . Lot of cool cards to try and work with. Took a while to understand how the bleed works and it seems there is a possibility of creating different builds. I focused mostly on shields and high dmg slash as currently it felt like the winning strategy .Dont think I encountered any bug or atleast it didnt break the game for me. What I thought was a bug is actually a feature where u can use only 3 cards from hand per turn. There is an indicator for it but initially it didn't stick out to me.
Visually for a jam the art works ! moving forward I would work with a palette of colors that are in harmony, which will help set a mood for the game. would suggest https://lospec.com/palette-list they have a nice collection of palette selection.
Overall a great job !! Cheers
