Thank you for playing and I appreciate the critique! You hit on a lot of points that I did consider during development, and some that are interesting to think about for post-jam development. A lot of time during the jam was just getting the backpack and items to work, and I did have a boss fight planned and some more enemies, but with little time left I didn't want to have any larger new things to have to bug test. That said, I think I will continue development, and some of your ideas will help inform that :)
