I like the idea of a rogue like, and the way the orbs are implemented, you did a great job working on that the only thing is that the bosses felt a little too easy, maybe you can add some more patterns to them, enter the dungeon-like. Good job!
The only problem that we faced during this jam was that some people found the game too easy and some people found it too hard. I think it is too easy but most people say it is too hard when they play it. So I am not sure how to balance that:)
