Glad I was able to keep the tension throughout the game and scare you!
I indented to maybe add some volumetric lighting to the game if I had time to make the scene seem brighter, but I didn't have time to add that.
I'm not quite sure of many other ways to show if the player is moving or not, there's already a sound that changes pitch based on movement. Maybe a coordinate system showing your location in X and Z values? If you have any ideas, let me know!
