Lmaoo I just played this a few minutes ago, And I was pretty negative during my first playthrough (and only play through) by legit using the hairpin to break into the theater room, and cutting the ponytail girls's hair, and of course putting the flower in the vase. When I first got to the other side I tried to use the hairpin to break into the door but it sadly broke, I honestly am so happy there are more ways to interact in the game that I didn't know about!
