Thank you so much for your feedback! I've never played Paper Mario but now that you mention it I see the similarities ^^
To all the posts/comments above (including this one) about the "final boss fight" I'm so sorry that it isn't working :(
I have a lot of patches/plans for this game and was unable to follow through a lot of it because of the jam's time constraint. 100% after the jam I plan on fixing this because there's actually more content hidden behind it that I want everyone to experience.
