First of all, I beyond love this game, it is by far one of the best I've played in a long time. I especially love endings 2, 14, and 16 so far. All the animations and art are amazing, I love all the little details and the facial expressions. This game has full force dragged me back into the original game as well, I've been having a lot of fun.
other than that, I'm a bit stuck on 12, 13, and 19. Any tips without ultra spoilers? (I have all others except 1)
