I also thought the revengeporn plot was way over the top for personal reasons. 'It's a game' works as a response to that.
...But it doesn't work for me for plot + mechanics reasons:
The kind of asshat behavior the MC gets up to for the 'best' result with the sister is completely at odds with his previous behavior. The same sister likes him being decent outside of this revengeporn plot. The plot + mechanics problem is that the game works on a scoring system - so I'm losing points for not acting exactly the opposite way I was previously being rewarded for.
Might I suggest either:
A) an alternate solution with less douchebaggery.
B) the party section have a private scoring system that doesn't affect the larger plot?
Example: As long as the PC gets Miss Bitch to admit it was all a lie, then the PC gets full marks, without having to utterly destroy them. That may not take much writing and artwork work as you'd just use a subset of events and images you'd already coded in the final video.
Problem is, right now the dev is slowly building sexual tension between the MC and the mother and sisters, so can't add right now hardcore sexual scenes with those characters.... but has to add some hardcore scenes in order of maintaining the attention of the players and not blueballing people too much.
The answer is adding sexual scenes with secondary characters: Zara, the model, or that Natacha. It's pretty difficult to make it naturally and not converting the whole scene in just an excuse to add a sexual scene, and I think that the dev doesn't succeed in that purpose. The whole subplot of the party becomes in a excuse to show an anal scene, and the resolution of it feels forced and makes the older sister a sick bitch and the MC a douchebag.
Actually, that's the problem with the MC: he manages to gain the heart of the females around by being charming, funny, supportive, and making them feel special and sexy, and that creates a good feeling in the player, but at the same times behaves as a douchebag by seducing all of them, and that creates a unpleasant feeling in the player... The fun in this game is to behave nicely with the women around, or to behave bad and cheat them without future consequences?
It seems that the dev doesn't actually know what to do with the MC, what kind of person is, and what kind of feeling want to inspire to the player.
Is this a game about a charming guy? About a douchebag cheating women? Is the game going to evolve to reality and at some point, the mother is going to know that the MC is playing with her and her daughters and going to kick the MC's ass out of her home? Is going to evolve to a fantasy world where a man can maintain an haren of happy, unconcerned women without being the sultan of the Ottoman Empire?
Maybe the game is a sandbox that allows the player to choose between being a decent guy or a douche. Problem is, if the player decides to be decent and follow only a path, let's say, the mother one, he misses 80% of the contents of the game so it seems that the game incentives the player to be a douche...
Just some random thoughts for the sake of talking. I know this is just a porn game and shouldn't be taken too seriously.
