Amnesia A Machine For Pigs - What was your favorite part?

[Kurton]

More specifically there was an area of the sewage level where you're walking across a catwalk and I remember seeing a red-ish fog as I approached a paralleling catwalk which then faded. A few seconds later I was climbing a ladder and I saw a quick flash of something directly in front of me and heard a sharp piano note.

I haven't been able to explain that; did you guys notice it too?

Those parts stuck out to me as well! I took a peek in that map with the level editor and it just turned out to be a pig mask appearing and disappearing in an instant. Caught me off guard for sure.
