Well, agree with the "allow the player to decide" thing. I know how bad it feels when you're playing a game you like and then you get content you just can't stand (like this game, honestly I'm glad I played this, it was awesome, and as a parody game this has a lot of potential, characters from basically everywhere can be included).
For me at least I really like the whole sharing thing, not even with just clones, just give ino a futa potion like Lazuli said in game or something and let's the fun begin, and the Nemona stuff could also be really cool. But that's for me, I know not everyone is into the sharing thing. Personally I think you need to do new things to keep the magic going, for me only Lazuli getting the fun is cool, but after a while you could get tired I guess, even if you're doing it with a lot of characters from different series.
But like I said, that's just me, that's why I guess an option to allow the player to decide what to do or even a filter (like the futa on male filter, btw, futa on male it's cool) would be the best for everyone.
