cumAgainGames, I just posted up a review and obviously I'm quite the fan. I did want to mention one concern that didn't really fit in the review because it relates to content not yet available.
Up until the then end of content (v0.2.2 at the time I played, so I'm slightly behind the times) whenever you upped the rank of a girl, new scenes would fully replace old scenes. Personally, I was fine with that so far because I really like vaginal sex in porn. So the progression and replacements suited my tastes. I imagine, however, that some folks might prefer some flexibility in this. I know that, once the anal content is in, I'll very much want to still be able to focus on the vaginal content (and perhaps still get any potential benefits of anal despite that focus).
It's possible you've already considered this, but I thought it was worth a mention. Thanks so much for the great game!
