Hi! This question is very difficult to answer, because I don't know what "proper horror" means for you. There aren't many jumpscares, since I don't like them that much, there's about 4-5 in the whole game.
That's fair, I probably should have defined that a lot better, haha. By "proper horror" to me i mean like, actively trying to scare the player either through your classic jumpscares or through graphic scenes (think Junji Ito). If it largely just sticks to the psychological horror aspects with creepy/spooky moments then I'll probably be a-ok with it tbh.
