This game is so good at mechanically evoking monster horror. It absolutely nails the feeling of crawling through the air ducts, taking out humans one by one, and inspiring terror in the rest.

As a video game, it's lackluster. It bucks Metroidvania conventions in a number of ways that don't work out in its favor, ending up highly linear and not taking nearly enough advantage of what could be very interesting combat puzzles. But it does some really cool stuff and I'm glad I played it through to the end.
