Interesting Visual Novel concept, I really enjoyed the world building that really makes you feel like you are in this devastated yet futuristic world, my only "but" would be that it takes too long to take off, I understand this is a long work but making the beginning dynamic in future works may be good.
Regardless, from what I played on the video (And a few hours off screen) I can say this is a good, enjoyable and interesting VN that becomes more and more interesting as you advance trough the story and everyone that reads this should give it a try.
