I thought the ghosts were the strongest part because it showed the story had the confidence to continue introducing new crazier ideas, and that one was particularly crazy but still fit into the SCP world. Sort of like why people liked Three Body Problem.
The weakest parts are when it focuses too much on the antagonist, where it tends to forget the actual definition of 3125 and just makes it something/someone that causes the world to end in random wacky crazy ways.
When it gets post-apocalyptic the writing also tends to forget how travel times and geography work. (Pretty common problem with old SF, where you'd go to a "planet" and there are like, 3 people who live on the planet. In this case the remaining living protagonist somehow manages to walk between very far places on his own without needing food and such.)
I disagree, this whole new plane of existence (basically heaven) was introduced out of nothing, without anything previously in the book hinting that something like that exists in this universe.
Tbh it felt like the author had written himself into a corner and made this up ad-hoc as a way to keep the story going.
It felt like a tie-in to some other thread in SCP canon, TBH. It's a pretty chaotic mix of ideas and stories, so it's something that fits but might have well been written by someone else in some other part of the wiki (chasing all of these is a time sink and a half, almost as bad as tvtropes)
