I think your game is perfect enough with the routes, I'd rather just options NOT to do things rather then add so may convoluted things (but I get it maybe some of those things are involved in the future so they would have to happen then fine)
PP size: You could make the size normal for most people don't have a huge one.... Why not make the small one in addition to that large one we already have. I don't know much about making games but it seems like it would be easier than making all of those additional routes and stuff especially since you have so many booty images and other images I don't see how it would be so difficult (couldn't you literally just keep the same image and shrink the size down OR as a fun thought can the other male characters end up with the girl you didn't choose and we can have a side story of them and they could have different sizes?)
IS this game about 50 percent completed? more or less?
I haven't read all the patch notes and stuff but also what is you favorite character since you are the creator? Is it Selena? She seems to have the most sexual and a sex scene so far as well (And I do like the fact we can decline or accept sex BUT also know kissing can be cheating as well... like I literally have not had a hug in real life in over 10 years LITERALLY so I would consider hugging to be cheating as well... So for me I don't know how to accept being so close to all the characters without feeling like I am somehow cheating in a single playthrough if that makes sense?)
