As far as I could determine by playing through the game twice, Campfire Tales is an extremely short horror story in which a few bits of text are randomly determined, but not enough to make any real difference to the narrative. Interaction consists of typing in some names, clicking a next-button a few times, and answering two open questions that do not, I think, affect the story at all.
The prose is at best barely coherent. Your group is, for instance, described in the following way: “They owned a collection of lonesome owl figurines and they spent their days dreaming about getting super fit.” That makes little sense, but a lot more than the next sentence, which makes no sense at all: “Most people would describe them as the merest person that they have ever met”. What? A few sentences later, I’m walking on “the parametric ground” and I’m told that “[t]hey culturally grabbed the nearest stone”. The English language should sue the author for assault and battery.
