The game looked really cool and horrifying with the usage of dark and narrow corridors as well as the repeating of walking in the same layout of the apartment. The game reminded me of P.T. and I would say that I definitely got scared when I played it the first few times. At first, I thought I was supposed to get caught constantly by the ghosts in order to proceed but later on, I realised that there was a pattern to the movements of the ghosts through multiple playthroughs. I got a little frustrated after playing a few times as I kept on getting caught by the ghost at the start but of course, I pulled through. (perhaps checkpoints can be added?)
The storyline is quite interesting as the ghosts seem to be haunting the main character and the speculation I have about the game is that the main character might have done something horrible that led to his friends becoming ghosts as well as the fact that he is constantly living through the vicious cycle of guilt.
Some improvements are definitely more storytelling through objects (I may have missed some of them if there are more) and probably more things that the main character can do with the camera instead of just using it as a flashlight. One more thing that I had issues with during the game was that I couldn't get through the door at times because I'm too fat or I didn't angle the main character properly XD so maybe the character model can be slimmer or the door can be wider (not really a big issue, just personal opinion).
Thank you for reading my comment and I wish you good luck in your future endeavours.
