I really like the idea of a monster you can't look at, and having to use lines of sight to block it off from places, but it was really confusing in the dark and twisted labyrinth of your game. I think it might work well as a 2D top-down horror game with a cone of vision, because it becomes a lot easier to understand your surroundings and you can also selectively show and hide things from the player. Overall, really cool entry! Very atmospheric.
