Forgot two others! The third I found was in the gallery/museum, where the True ending's name is shared with the same name as the Glutton's Ending (Ending 2). That name being "Gutslut" which should be for Ending 2
The fourth I found was regarding the mirror not matching your character's appearance when she gets her clothes back after defeating the Beast. Any mirror you look at still reflecting Anne with her massive plump breasts despite wearing new clothes in the aftermath.
