I've played a handful of horror games and I was feeling some fear! The atmosphere was great. The "notes" that I found were confusing to understand so didn't really understand what was going on or what the backstory was.
I thought you did a great job at the buildup through the environment and sounds. I wasn't sure if I finished the game as I got lost and couldn't find what else to do, so I was hoping for a more satisfying ending.
EDIT: I realized that I posted spoilers for the game so I left out a lot of the details.
