I've played this on a game site with the game embedded in the page--whatever that type of game site is called. The game was OK until every auto save stopped loading because the game kept either lagging or crashing. When it was working, the only thing that would make the game better is if the dad wasn't so stupid and fuck his youngest daughter first. I've reached the point where he's fucked his business partner, his sister, and then his business partner again, and the youngest daughter is still untouched.
Now that I've found the game here, I suppose I'll have to start from the beginning all over again, but despite the dad's stupidity, it will be worth it.
