I really really liked this one... actually I don't know if I liked it. :D
It has an absolute amazing atmosphere.
I liked the environment, it was really tight and the hallways were really scary. You not being able to see anything 5 metres in front of you makes this game really terrifying.
I also liked the graphics style, was pretty cool.
The sounds were alright but what got me the most were those real life videos/pictures... with that one guy shaking his head weirdly at the train station and all the others aswell. I did not expect that at all since it's a pixel game but it was really well implemented! I was really scared of going out of the rooms and it was just disturbing and making me feel really really uncomfortable. And when I died for whatever reason and wanted to press "Replay" I got jumpscared SO hard I threw my headset away and that literally never happened. Also that first jumpscare where they hand came flying towards you was pretty good too!
The monster design was kinda meh (the one who was walking around) but maybe it's also just the silly animation that it had.
There is a bug: You can't go up the stairs sideways (using key A or D), you will get really really slow and it would take you literally minutes to get up. So you have to look forward and press W when going up the stairs. Not gamebreaking but worth mentioning.
The voice acting is okay, it was cute ^^
The biggest problem of this game is that you can not tell if the heart sounds (or even the step sounds of the monster) comes from upstairs or downstairs... so it's kind of annoying and frustrating when you look for the heart downstairs but realise it's actually upstairs or when you don't know where the monster is (that's literally why I died, I got out of the "deamon world" and the monster was right in front of me).
I didn't fully finish the game and after the second try I just gave up because it was too terrifying and I didn't want to see that uncomfortable footage again. That was literally the worst (best) part of the game.
9/10 = 5 Stars! :)
