User blog:Cornconic/Does anyone know the name of this pasta?

It's one of the best ones I've ever read, yet I can't seem to remember the name. Here's a description:

It's about a man documenting his experiences as the only sane person in a world where people are eating rotten meat only for their heads to swell up and giant flies to burst out. There's a section near the end where the protagonist has to fight these weird meat creatures as he's going up a tower (I think? I read it a while ago).

I know the description's kind of vague, but can anyone tell me which pasta this is?
