I'm usually not big into horror games, especially those that abuse jump scares and monsters constantly tailing you. I'm more into atmospheric horror, borderline mindfucks.
Thankfully, Human falls within the latter.
From the word go, you know some serious shit's gone down. It's not the scariest game ever, but it does its job by keeping the atmosphere dark and tense. What lies around the next corner? The further you go, the more tense it gets.
I do think it dials it in a bit early right before the end, dropping the climax a little too soon. However, the ending isn't disappointing.
Overall, it's a great experience. It has one simple goal and it achieves it well, even despite my only criticism. Very well done!
