Thank you for playing! The idea of adding points to pick a specific character is clever, I wish I had thinked that, nice!
Overall the game is not polished as I whished, not only the things that you mentioned but some others, but we run out of time to do the fine tuning we liked, I will address some in a post jam update, others I think, only if we ever made an 2.0 update expanding the concept (maybe adding your upgrade idea?)
