Very rust punk-y indeed. I loved it so far, but there is still room for improvements. What I disliked about the VN was the buggy rides. You seemed to use it as a pause from the action so you can better explain the characters and places of your world, and something about how that was delivered made it feel like a boring chore to read through. This is just an idea, but what if you had the MC dream about those moments, so instead of 'explaining' things to the reader, we could live through them ourselves from the MC's perspective?
In my opinion, as a reader, I do not like long moments where the writer dumps information about their world and characters/events. These notes should be kept to the writer and then thought of a fun or exciting way to show the reader those things, rather than explain it to the readers like it was a lesson and the VN is the classroom. It is interesting, dont get me wrong, but information dumps suck when you are the reader who expects something a little more, in terms of standards.
Good luck and please keep it up. I really enjoyed this VN and cant wait to see what happens next.
