He's implied that he had more story to tell following part one on the night of the typhoon. But, has since decided to skip it. (He made it sound like this decision was influenced by his followers feedback. A lot of people seem to not care for the slow build up he has been doing to get asuna to the point she will be unfaithful. And want the corruption to happen faster. It's still the same game and made by him, it just seems like content he intended to originally include will not be there.
I understand dropping side stuff if it's not important to the main plot, but dropping main plot stuff seems odd, and i will no doubt find plot holes (Not that they don't exist already.) In any case I'm sure I will enjoy whatever he ends up putting out in the end. But, it will leave me wondering at what we could have had. I'm not upset about it or anything, just sharing what I have seen in comments on patreon and in forums here regarding the speed of his updates and the contents within. He seems to be rushing the plot to make people happy, and the only things that can suffer from that are Fujino himself and the game.
