Level 17 was suppose to be infested with only spiders but that idea was dropped. No skins for Annie unfortunately in her gameplay. Well, maze part is reserved for Hailey but there will be interesting final level for Annie. Masturbation option was added without any thoughts since it was there in Parasite in City game.
I think the milk you are referring to is not implemented well. It's suppose to heal Annie for 30 seconds.
