I disagree with previous posts on the attitude "changes" of the MC. I think you do not understand the point system, which is more interesting than most other ones used in adult games.
You probably feel you have to always go for the choices that give you points (the one that makes him seem like a pussy) rather than what you want to do. And this is a weakness of a lot of games as yes, those force you on certain choices.
But it's not so at all here. You have to make ... choices. When do I act perverted? When do I force things. You HAVE to do choices that cost you points if you want to take advantage of that system.
If you just act "weak" you accumulate those points but they won't go over ten... So they end up wasted. So you have to do some yoyo between 1 and 10 to see everything, of course while avoiding going down to zero. Even getting caught won't make you miss much, you'll just get closer to zero, and probably will have to give up another perverted chance to increase your points.
And I find this perfect for the game. This is your daughter, you don't go down on her all perverted from the get go. There is a line, and you have to be careful. The line here is reaching zero by acting too perverted.
You end up seeing just as much anyways. I played the system, forced the dad on the daughter when they were drunk, peeped at the right moments, and I still finished this build with 7 points without cheating.
