If you've got a sensitive stomach I would probably hold off on playing/watching this one until after lunch or dinner because it gets pretty visual and gross (this is a good thing). Pumpkin Eater is an amazingly cool experience and it's not often that reading something can gross me out to this degree, especially when I work with things of this nature and have been exposed to it a ton already.
If you're into body horror and visual novels, playing this game is a no brainer.
