I think the best thing about this game is how utterly dedicated it is to whatever it has going on, from the weird mish-mash of German-Chinese sci-fi aesthetics to the puzzles being esoteric as hell to even it calling you a wimp for not playing with its extremely limited inventory.

It deserves props for taking all the right lessons from its inspirations (which I assume are Silent Hill and Lovecraft with maybe a dash of Resident Evil), building itself around the body horror of monsters and escalating the tension of them being a constant threat that you have to work around more than fight through. All around the solid core of what makes most horror stories good: a human desire to see things through because of people you care about, and Signalis definitely makes you care, even if it is out of sheer curiosity as to what's going on.

It's not perfect (I personally think some of the puzzles are too complicated and the final boss just sucks), but that doesn't stop it from being a must-play for anyone who would call themselves a fan of the genre.
