This comment is probably overreaching as I'm sure you have the main elements of the game locked down, but I'd say the entire mechanic of being chased by the shadow person(s?) is unnecessary. The general atmosphere and area design is nearly perfect, and it would be fascinating to see how you could build suspenseful situations and challenges based only on the environment (visual and audio) rather than resorting to the pursuit mechanic, which has been done to death and doesn't really add anything to the experience. I'll leave it at this but would be happy to throw out some specific ideas if you're interested. All that being said, it's looking and feeling great and I'm psyched to play the final game when it's out! Thanks for reading :)
