Even that it has an Incest tag, this VN is not about incest. That Nika and Nami are not Nojiko's childs is obvious and within the story it is mentioned that Nika and Nami have different parents.
That tag should be removed from my point of view!
As well I am sick of all the rework complaints. Ocean did not like the rework
either as he has written in one of the updates. But he was sure that he had to go though this because he wanted to deliver the best possible experience on Steam, GOG, et. al. He was convinced that if he would deliver at first an inconsistent or only half baked first part of the game on these sites then his reputation would be seriously damaged and it would be much harder for him to release later a second part.
The easiest method to get faster updates is to support the dev, either by buying the game or by supporting him regularly. Those who don't have the financial means could at least make the effort to write a constructive review.
