I expected this game to be a good time, being essentially a threesome of Resident Evil, Silent Hill, and either Neon Genesis Evangelion or Nier: Automata, and I was left bored, confused, and disappointed. I do have some positives though, despite my negative experience

+ The puzzles, most of them at least, were actually interesting and creative. The X-Ray with the card and the Microphone in the deeper areas were some of my favorite, though the final puzzle was annoying with all the back-tracking
+ Visuals were really damn nice, especially when the game goes first person, subverting a few expectations I had going in
+ Music, while being a bit too similar to Silent Hill, was good at creating tension, even though it was too sparsely used in normal combat due to how easy the combat was and how easily you can just run from literally everything

I do have a lot more negative things to say than I do positive though

- The game is too easy, given the prior "You can just run from everything" statement
- The six inventory limit, and by proxy the immense amount of backtracking, ruins the enjoyment of the game. It adds tedium, not tension. The areas and the enemies don't give a real threat to think backtracking is worth it
- You can get locked out of areas with no warning at certain parts. Example being when you get the elevator key card. There's ammo for the shotgun up there, but you don't have one. Thinking you can just go back, you head down to level three and you can't use the elevator anymore and, lo and behold, the shotgun is there; With no extra ammo cause you didn't think you'd be stuck here or that the gun was even this close
- The story is a complete mess that leaves way too much up to interpretation to be even a bit enjoyable. I spent the entire game thinking this was like Dead Space: A mining colony finds an artifact or a long-dormant virus that infects the area, driving some mad and the rest to kill as mindless monsters. Nope... it's much more confusing and only a little speckle is given to you
- The endings... I won't explain them, but rather the method to unlock them, except the "true" ending. It makes me hate the main character a lot and it frustrates me to no end
- The enemy design seems to take way too much inspiration from Silent Hill than it should. Basic enemies look like Nurses, the leg enemies remind me of the Closers, the boss in the deepest area is like Abstract Daddy mixed with the cage monsters

I really wanted to like this game, especially since a lot of people are saying this is the next step in the horror genre. So was Callisto Protocol, and that game failed on launch. I'm not saying Signalis failed on launch, or at all, since it's at 97% positive, but to me it fails to capture me on the themes, story, characters and gameplay. The Dead Space remake, Resident Evil 7, even Barotrauma are much more scary, have a more coherent story that people can understand or theorize about, and doesn't make gameplay revolve around backtracking every few minutes because your inventory was full on the supplies it handily gives out on a dime.

Don't let the negative review of one person stop you from loving this game. Personally, this is not what horror should be going forward, and that's just one man's opinion
