Good! Pretty good in fact!
One of my biggest gripes on this wikidot is when authors try to use a fourth wall break or arbitrary interface screws to evoke a reaction. It usually falls pretty flat and comes across as awkward, not to mention flows against the format/framing device that it's supposed to be a survivor's almanac.
Not this one though. This is a textbook example of how to do both of those things well. It fit in and flowed well into the article, and there was enough interesting detail that it wasn't the only notable thing about it.
I really love the idea of a Level that humans can observe but basically have no means of physically accessing. It's like a hidden, unused texture or door in a video game and matches the Backrooms VERY well. The hidden credentials also work really really well here and do a good job of making MEG feel skeevy. The plot twist was pretty cool too! I'll have to go back and read that level to see if it was foreshadowed there!
The only thing that I might hold against the article is that it's dangerously close to SCP in tone, but it's still separate enough regardless.
Kudos!
