Hi there, thanks for sharing your story!
I can tell you put a lot of thought into the backstory of your world and how things work, which is great! Your descriptions are good and really help to highlight the mechanized nature of your world.
My one big suggestion would be to introduce your main character in this first chapter. Right now all I have is a bunch of random citizens, the two boys, and 'they'. With no names for these characters and no set point-of-view, I'm getting lost in the descriptions and struggling to find the direction of the story. Is one of the boys the main character, or is it this other person that showed up? Or is it someone else entirely? I have no idea at this point. I think if you make sure your main character (if they have already made an appearance) stands out as the POV character, I think it could really help the reader along in the story.
That's all I got for you, thank you again for sharing!
