Well, since this thread is back to the frontline, I'm going to take the opportunity to mention that it appears that the author is working on a new game, according to his ci-en page. There's a tech demo, with no erotic elements yet.
If I remember correctly, I think they were getting a new job or something and didn't want to get traced back to the H-game. Covering their tracks, so to speak. I also remember that they had to change a couple of the animal enemies cause bestiality was a no-no with one of the places they were selling the game on.
