Not 100% sure, but most people agree that it was probably a simple jump on the incest hype train and after he noticed that people don't like his NTR stuff he didn't know how to continue and then just abandoned it because everything would be completely impossible x'D
I don't think so, because even after you get rid of Eric there is a lot of story going on so people must had supported it back then. And NTR was mainly avoidable except 2-3 scenes.
I read some comments from past pages and now I think ''patreon'' was just an excuse. Because he could simply change the family names to names I wrote(landlady, flatmate etc.).
I read some comment that says ''He didn't like incest stuff and don't want it to continue''; like WTF!? Ahahahaha. Then why he created it in the first place.
Like I said, some comments says that he used this game as a cash cow to produce his new -for me uninteresting- game. And use patreon as an excuse to abandon this and start his new project.
It is a dick move from his side. I don't know how he found support after this fraud.
