Spent some time on this recently.
It's atmospheric as all hell, and the audio visuals are excellent. What it really lacks however is a hint system, or some form of guidance/structure.
A lot of the time it's a real guess wtf you're meant to be doing and hope you're on the right track sort of experience. Not bad exactly, but easy to get lost or spend time wondering what exactly you are meant to be doing, which is making me worried I will be completely lost when I go back to it lol
