Had a lot of fun messing around trying to see how far I could go, unlocked all but Witch Fairy. Movement with the Brave Fairy was probably the most fun for me, got moving extremely fast but able to stop fast if needed! Also not sure if there was an update since the known bugs were written but double tapping Esc worked for me in order to easily swap characters, though gameplay and music still persisted until swap, even during rewinds.
