S1 was my first game of this genre. It was fun, there was a bit too much provocation, but overall it was entertaining.
S2 was really good, especially towards the end of the game. It was really fun to clap your hands to bring another MC into the party or sex scene. 
A small example:
Jessica (my favorite girl) always complained and annoyed me, but secretly she always wanted my dick. Especially when she was drunk 

If I can repeat a day as many times as I want, why shouldn't I give it my all and exploit or find out every “weakness” of the girls?
For example, with sex toys (hey, there was a sex shop in the game^^) or maybe with BDSM elements (there was a special room for that).
It always felt like I was holding back instead of moving forward.
IF I were the author of Season 3 (after Megan and Zoe's part):
The day starts to repeat itself again, now I know a lot about every girl in the game.
Zoe, who loves me, would do anything for me (options for threesomes or foursomes, with toys or BDSM, not with Megan, more with the other girls. The sex scene with Zoe at home was good, she showed more of what she really wants.
Good start!)
Jessica and Chloe are both fighting for my cock, so they have to live out their dirtiest fantasies. 
And so on. 
PS: 
When I play a game and one of these girls says “harder,” why does it always mean “faster”? 
Why are there no options for spanking, choking, DP etc.?
That would be a form of harder, wouldn't it?
Just my 2 Cents
