This was TERRIFYING. I was so scared I had to take out an earphone and leave the lights on haha. Some games rely on jumpscares to scare you. This game makes EVERYTHING you do feel scary. I felt uncomfortable, terrified, uneasy, and I even looked behind me a few times.
If you want to fully immerse yourself then follow the rules. I couldn't because I knew I wouldn't be able to finish it haha. My lights stay ON.
