Well I caught back up to what's been released (chapter 37) and I have to say... I don't think I like the way things developed.
Specifically with the sudden flood of Planetary Human content.
The recent reveals of the Planetary Humans and the backstory of the Main Character may have been exciting for some people, but I would absolutely expect that that reaction would be from someone who has already read all of Planetary Human.
And while the user Kendama, the uploader and translator of the story onto this site, has pointed out that reading Planetary Human could certainly make things make more sense, I had not, and it's very likely that this story is the first exposure to the author that others are having as well.
The way the Planetary Human stuff was brought up in-story had a very different tone to the other mysterious events of the story. Unlike events such as the initial appearances of the eggs and the transformation of humans into the smilers, the Planetary Human content felt more like something the readers were expected to have some level of knowledge of the characters and power system mechanics involved, which a new reader would be completely unequipped for.
Furthermore, the sudden introduction of two new characters who are both being heavily implied to have long and important backstories, as well as the very dramatic shift in the original Main Character's personality (the revelations he made about his actions actually make things more confusing and contradictory, not less), made the following events feel like they were from a completely different genre and completely eliminated the relatively low-level feeling of the story.
No longer are we following the struggles of normal humans in a world gone mad, but instead we're watching as superhuman beings throw lightning and fireballs at each other.
I think that one of the things that really made things awkward was when the Dog-Man talked about how he was actually a Planetary Human the whole time and that there are lots of them around and that all of this originated from Planetary Humans and Planetary Humans are heading towards the city and basically the entire Apocalypse Live setting has been overthrown by the Planetary Human one.
It just felt like a massive shift in tone and direction, as if the author decided that he was done playing with these new toys and wanted to go back to his old reliable ones, so tossed this story aside.
And I get that maybe this was the original plan from the start, it totally could be, but if so it was a very unsatisfying thing to experience for myself.
An equivalent would be something like...
It'd be like if you were watching Neon Genesis Evangelion, but then the final episode revealed that secretly the entire plot was actually caused by the ripples in space and time from the final battle in Naruto, and then the story starts constantly dropping references to Chakra and how everything from the robots to aliens were all caused by Chakra this and Chakra that. Everything was actually Chakra this whole time.
It's completely out of left field and just leaves you sitting there awkwardly, twiddling your thumbs as you hope that the robots come back, and wondering if the show actually just committed to turning Shinji Ikari into a raving psychopath who can now blow fireballs before then killing him off.
Now apparently there are like 3 chapters left, and I hope that they'll really help clear things up... But that'd be 3 chapters to help me understand exactly what happened which I'd need without using lots of Planetary Human background lore to understand.

tl;dr, If you've read Planetary Humans you may enjoy the twists near the end, but if you didn't then you'll just end up confused.
