This is such a great game !
I have some trouble achieving the third ending though... I've tried multiple combination of choices, so I'm guessing I have to do something really specific, but I can't seem to get it. May I ask for a hint ?
The endings I already achived are (SPOILER WARNING) the first one where you stay in bed and the second one where you return to your room after saying "you don't have the courage to change"
