Sounds like your standard creepypasta alright. That kind of thing always seems like it best suits an anthology series, shorter episodes that just have fun with the spoopy atmosphere and can hint at more without having to strain the concept.

The movie was made by Kane Parsons, who prior to this point had a series of short films on the Backrooms that I guess still had too much lore rather than evocative hints, but is somewhat closer to what you’re describing because they had less overall continuity, with each video being more like an individual event involving different people (usually, mostly) in a broader escalating situation.
