hello! Thank you so much for playing the game!! Essentially, you need to find 6 books and return them in the library room. You should be able to find 3 books at the beginning of the game then three books after the “basement” incident. If you have other questions, let me know!
Oh, I see! It looks like you’ve passed the point of no return! Once you interact with what’s underneath her bed (it asks if you’re sure you want to do this), there is no returning back to the other rooms and it leads you outside. You are locked with the other ending.
