Definitely, but said spookiness is also completely without violence or gore or any real "horror" tropes other than trying to stealth your way through dark hallways.

(Light spoilers) Supposedly the design intent was that you're not supposed to stealth in the dark much at all! It's really not obvious though, so it's a bit of a failure of design in that particular aspect. Interview with a dev: https://medium.com/@cordialkobold/interview-with-alex-beachu...

Still spooky atmosphere for sure.
