This is a teaser, a bit like how some stores will have a little sample to get you to buy the product. The completed first book is on Steam and it's 7 chapters. I'm not a Patreon person, but I think chapters 8-11 are available on Patreon. As for when the completed 2nd book will be released my guess would be when chapter 14 is done sometime between today and the 2nd coming. As far as a review, I really like the game. The writing and animation are both very good. I bought it on Steam and I don't regret it at all which is a lot more than I can say for some of the schlock being made in the genre.
