After playing through the rest of the game, one general piece of feedback I would give is to insert a few more choices/interactivity even when they wouldn't affect the outcome. For example, when Alice is talking to the rabbit and it says she tries to interrupt him, you should let the player choose something to say to interrupt but the rabbit just continues monologuing. Additionally, having a little more agency would make it more impactful when that agency is taken away, such as when Adelaide is in the sky.
I think Adelaide's character gains more depth as the story goes on, she seems like a somewhat reluctant, somewhat sarcastic protagonist. I still think the ending has to do with identity/its suppression, and I like all the NPCs, they really add to a cool, intriguing mood!
