The mood here is unparalleled, I was terrified and checked the window constantly. Even after checking the comments and about the game section to know how to get more endings, I still couldn't help being paranoid about checking.

The good ending keeps the creep factor while letting you feel some relief, and the bad and true endings are truly upsetting.
That said, I found the fact that 'he' comes more for your phone than for you specifically a bit odd. Is the creature after humans but interacts with them solely through eletronics? That seems a bit overly specific... Is it attracted by signals and attacks humans once it finds them? I don't know, it just felt, odd.
Still, an amazing and atmospheric story delivered with strong visuals and good gameplay. I enjoyed it thoroughly.
