The game isn't about trying to fuck your step daughter though. You CAN mess around with her, or you can choose to avoid her as I do in my playthrough. I wouldn't have the option to avoid her if the game "was about trying to fuck your step daughter".
I respect your opinion, but I disagree with it. Of course the game allows you to reject the stepdaughter, but clearly the main theme is her, the others are just extras, in case you don't want the stepdaughter.
At least that's what I noticed until a few updates ago.
I didn't play the last two updates for the reason described in my last comment here in this thread. So I don't know if the direction of the game has changed since then.
I'm just taking a look at the images and animations (unzipping the files).
And speaking of that... I don't mind lesbian scenes in games, if they're well done, I even like them. But from what I've played, the scenes (the lesbian scenes with the stepdaughter) that I saw in this update are completely meaningless and maybe just inserted to please. As I said, I haven't played recently. Unless the developer did a good job with the story about this scene, I don't think it fits with the stepdaughter.
