Don't hide score, level progress bar, and current level. They presently hide after a timeout from picking up an XP orb. Sometimes I want to see my score without having to go to the pause screen, or see how close to a level I am at times when I haven't recently picked up an orb.
I see from discussion over in #game-dev-help on Discord, Chim has the philosophy of hiding distracting elements, well, I'm in disagreement that these elements are beneficial to sometimes hide and sometimes show. You could say "make it an option" but how many hundred options is too many options...?
