Superb execution, interesting premise, a bit of a bookshelf problem, but that's no issue, especially after making me paranoid about my neighbors.
Freakishly great atmosphere. I was fully immersed right from the beginning. The interactions in the game are neat, well thought out. The story of the apartment seems a bit spooky, nothing serious, although I think it has a potential to be a very serious, more psychologically centered game, but it definitely delivers on the scares. Great job.
Best of luck with the future projects.
P.S. The comment below me is actually a gameplay done after I published mine. I made a video 5 hours ago and the video on the previous comment is published on YT 2 hours ago. I am not saying that the person saw the bookshelf issue and had the exact same problem, but just FYI, I encountered the bug first. Yeap.
