I'm kinda done with the godling lore
The mythology is overpowering and it was never essential to Hand Jumper's thesis in the first place. If you're not a fastpass reader, you might not agree. I initially thought that the godlings would be a great way to explore Sayeon's own god complex, but it's shaping up to be just a world-building construct in a world that is already built enough.
I think HJ is trying to use godlings to talk about what the value of "humanity" really is and why perfect beings still desire the imperfections of humanity. However, you don't need to borrow the idea of selling your soul to the devil to do this.
HJ has already done it in a much more unique and natural way: through Sayeon, who has already lost a lot of her humanity in her quest for perfection after being given the power to achieve it (time reversal). For example, she rewinds just to have a perfect conversation, only to discover that she's lost the whole point of having a conversation (building genuine connections) and further isolating herself from the people around her.
HJ's beating heart is an exploration of ambiguity in morality, on a personal level with Sayeon's psychological collapse and ability to rewind time, and on a bigger scale with the idea that the oppressed class is manipulated to be complicit in social institutions that perpetuate violence and hierarchy. Godlings don't really add to that.
In my opinion, the best move is to expand the story vertically instead of laterally. It could use less new ideas and more depth in the ideas that were already developed.
