I try to be as creative as possible, but I am always inspired by things that I see and read. The At Last Alone world has a bunch of different inspirations, but I won't go into those here. Instead, here are the inspirations for this particular game:

Final Fantasy Tactics Advance, one of my favorite games.

The Russian Sleep Experiment, a creepypasta that has always stuck with me, despite the plot holes.

The "Risen" storyline from The Mysterious Package Company, which is where I obviously got the title.

Kuru, a prion disease.

The Kodiak Crab Festival, because, if you weren't aware, At Last Alone takes place in southwest Alaska and I thought this would be fun to reference.

Fatal Familial Insomnia:
