Oh thank god, I got through it without that thing getting me (If I just keep looking at the wall there is nothing there, NOTHING THERE!). I managed to get to an end I think, there was a thanks for playing, - beyond that my heart can only handle that once. For keeping constant tension, and continually dashing my hopes of being able to remain on linear, open spaces off the ground, I have to give full marks for the horror.
Fun moment from my playthrough: Which root should I take? Sees a shadowy figure casually turning a corner out of view on the building next door... UP UP up up UP UP UP!
