I am wondering what happen that this game is now abandoned ?
While it is tagged incest from the way the game is reading there will be no incest in it.
Due to the fact that not only he told Fuyu that if she was his daughter he would not be with her because incest is wrong
Also his sister told her daughter that she is not blood related to him so she could do things that his real daughters could not do.
That of course made me unhappy about it.
The story is nice but now you got his own sister trying to destroy his family just like his mother would try to do is not good either.
I know if the youngest daughter had done what she did to his sister's daughter then I would have tanned her ass so she would not sit down for a week at the bare min.
1) What happened to the game is a lazy developer, who reeks in the profits some simps throw at him. Guess he will only start to "work" again when and if they stop giving him money in significant amounts for literally nothing but lame excuses and broken promises...
2) There IS incest in the game with the patches for this content, as goes for pretty much every game with this tag on this site / Patreon.
3) Storywise the things you mention are about subjective opinions. Guess everybody has his opinion on these things and they may differ. All of these have been discussed dozens of times here, nothing new to get from it.
