This is so amazing and interesting story. I hope author is alright, because it's been a long time since the last update. May i ask a questions of how many chapters will be in the book one, and when expect new updates?
The author is regularly posting on their Patreon (and replied to couple of posts here just a day earlier) so yeah, they're alright. It's just the public version of the demo has pretty low priority, so it doesn't get updated very often.
