I was one of the players KingDunnad ran this for, and it was a blast!
I am usually concerned when stories reveal the central threat is benign, but it worked for me and my fellow player. The reserved threat, the disparate clues, the random interludes/events, and the starting amnesia successfully pull double-duty at letting our minds fill in the horror while also justifying the twist when it’s eventually revealed.
With the right playgroup, this is an excellent paranoia-fueled horror-comedy scenario (with the players as the butt of the joke). Great job!
