Creepy atmosphere. The sound design was great.
I might have missed the death game theme aspect.
The game froze up near the "is that me" message, when you come across your body. There was a lot of clipping. I even fell off the map near the table in the upstairs room.
You should let the player use left/right click instead of f/p. Also, the title/menu screen looks so bland compared to the rest of the game. That's an easy fix.
