NonsenseHumor said his first FNF mod took a month to finish. That comes from the mod’s official itch.io page, which states, “this mod took me a month to finish.”

Quick Scoop

So the short answer is: about one month.

Context

A later release note for the same mod mentions that the final update came after “two years of procrastination,” but that refers to the broader development of the project, not the first mod’s initial finish time.

“this mod took me a month to finish”

TL;DR

  • First FNF mod: 1 month.
  • The longer “two years” note is about the later overall project timeline, not the first version itself.
