I was very surprised by how unnvering the atmosphere you've managed to create. That thing really scared me, multiple times. I think the audio cues were used well and definitely contributed to the atmosphere too, well done. Only nitpick is how slow it is to jump onto a ledge and then hoist yourself up, but that is very minor and does also contribute to the suspense. I liked the opening scene too, definitely up there of all the games I've played so far.
