I played this without the patch and was pretty confused as to why there were no erotic scenes until almost the end. Then I came here for clarification and saw the posts talking about the MC's dog dick which made me even more confused. Played it with the patch and when I got to the sex scene I was mostly indifferent to the MC screwing with a doggie dick (playing porn games for a few years has made me see some weird stuff before).
So my only question would be why change the MC's dick in that way? If the idea was to show that he is suffering mutations, he could have kept it the same, but changed it's color. Make it black, like the hand. This way, people wouldn't be pissed as much. Or if the dev really wanted to make that change, at least do it around the end of the game, not before boning the MILF that is the center of the game.
