This was a relatively quick Neo Twiny Jam entry without too many choices, but what were there were quite funny. A lot of details aren't filled in--you've warped to some odd reality to track down someone who's, well, been warping through realities too much. How strong their essence is, you don't know. They only give cursory excuses. It's unclear whether they're evil or ignorant.
That said, you have a job to do, and there's some mystery as to if anyone is at the typewriter.
The ends are abrupt, and that works for NTJ, because they needed to restrict the word count and also provide a few passages through, and because it's about the apocalypse. I also enjoyed the detail of a portal folding into your pocket--it's good surreal stuff presented quickly.
Despite giving relatively few branches, DGtT got me thinking of what its universe was, how it was built, and so forth. I enjoyed it on its own, and making up my own backstory, which seems to me proof the author used their words well. But I would still enjoy reading how the author themselves would've expounded on it.
