I liked this one too, and it's an interesting sequel to 6932. That being said, I think it's too much of a sequel, which hurts its standalone properties a tad bit, especially around the beginning, and the reveal with Kuro, which means nothing if you haven't read the first one. Maybe it wouldn't hurt to make a nav for your series, use maybe the Earthworm nav or ANT? Feel like that'd help a lot.
Anyhow, onto the piece, it's a tad all-over-the-place, which I wasn't a fan of: I feel like the first one was much better structured. The story is really solid, which I liked, and it had some good bits, but the ending was kinda lukewarm. Not sure if the collected items was the best way to end this piece.
Nonetheless, it was a good read, so it's still a +1~
