So,
I found some typo ( 1 currently)
Near the start when your sister come in, It create some kind of loop a bit latter on, if you choose should i have to fly with her it bring you back to the good morning. But choosing the right option make the game select the left one.
The flowery frame around the portraits is missing in the dialogue in front of the library door.
Baxter bag description as typos.
Baxter dialogue is missing it's window, reappear after looking up at older sister.
Also when loading the next part the screen turn partialy black with strange geometric motive in the upper left part.
There are some He / She missused.
The game is enjoyable, i will post more discoveries as i play trought it.
