This was a fun take on childhood (and adulthood) fears on dark buildings and spaces, never knowing what lurks behind a corner or at the end of the corridor. The use of liminal spaces felt cohesive throughout in an oppressive way. I'm not sure if I did something wrong, but I never saw any creatures? or maybe it was the intention to make the player paranoid without any monsters lurking with the possibility of running into one? Nevertheless, I think the beginning could be expanded to its own game with a few floors and apartments to explore. I spend a lot of time trying to open the doors and just going back and forth in the corridor built tension for me at least! Great job, you used the dark in a very effective way and made it feel very creepy in a nostalgic way!
