There are indeed no cheap jumpscares, but I can't guarantee a monster won't surprise you around a corner or something.
As a side-note, it's always super-cool to see the "creep factor" have some sort of effect. I'm a bit of a poor judge of such things (I don't get scared easily, cheap jumpscares notwithstanding), so it's mostly me just chucking in things I think are cool+interesting+whatnot. It probably doesn't help that I fairly-regularly browse the SCP wiki before going to bed, though.
[EDIT] Oh sheeet, this got 2nd place
in the Vinesauce compo! I should probably do something to celebrate. o:
