Hey thanks so much for the feedback!! I really like how thorough you were in the post. I'm not sure that I will end up updating the game in the future, but if I do it'll probably be to add a save function and visibility of the item tracker in the pause menu! As far as the finding out more information about the characters, they will be expanded on in a future game. If you found all 9 notes you'll probably have found a decent amount but definitely this isn't the end of these characters!
Again thanks a lot for the feedback it's super helpful!
