To be honest, I agree with the previous comments. The atmosphere is very well done, and if the goal was to create discomfort, you nailed it. I can see this evolving into an ARG or something deeper behind the game.
However, in my opinion, the character jumps very high but moves very slowly. This might have been a gameplay or narrative choice, but for me, it made the game feel a bit tiring to play.
Congratulations on a great job!
