For the (very few) horror games I've played this has to be my favourite one, with its relatively small scope it's polished pretty much to perfection. The low-detailed, atari-esque graphics is a genius choice for the genre and make the rotoscoped cutscenes/jumpscares feel jarring in the best way. The controls and game mechanics are really simple (four moving directions + action button to exorcise) so all your focus is directed at the atmosphere and story. A couple of the boss fights took quite a few attempts to get through which brought me out of the horror for a bit but its really good at dragging you back into it afterwards.
I'm currently halfway through chapter 3, can't wait to see how they wrap this up

TLDR: those fnaf interludes WISHES they were Faith
