I remember playing a horror game, in 2D pixel art style. You can choose to be a boy or a girl, both have similar appearances. The game takes place in a school where a girl with purple hair haunts the school (it seems that the students there bullied her in the school bathroom, where she took her own life). You had to solve several puzzles to discover new places and get new items. You could also die! I also remember there was an old man (or something like that) who saved our game or he said something about that girl (I don’t remember well). He had a secret tab where he told you something to solve one of the puzzles. And finally, the last thing I remember is that the name of the game is the name of the girl who haunts the school.
