Well, took me some time to see your reply lol.
First of all, like I said in my original post, I am a fan of your game. I have no intention to not play your games going forward.
I also do not wish to see girls die or taken away. Nor do I want drama to just exist for the sake of drama. However conflict is useful for many reasons. For starters, how will your game end (please don't actually tell me)? Do you have a plan for this? Is it just gonna fade to black at some point, or are you just gonna say "meh, good enough". Conflict serves as a useful guide for allowing your characters and the story to grow, and eventually have an ending.
Furthermore, what is the point of several of the characters. Since the Maddie storyline ended, she hasn't shown up very often. When she does, it is just in a supporting role with other characters. A few sex scenes, to help introduce a character and move her story forward, and thats about it right? Sure she was in that scene where she asks you not to be overly angry with Mary, but honestly, she simply played a side character along with all the other family members who have also played minor roles in the Fiona v Elaine story.
Conflict, even minor conflict, serves as a glue of sorts, keeping characters grounded, alowing us (and you) to learn more about them, for them to grow, and the relationships to florish and stay fresh for everyone.
As for characters, the ones you mentioned are sound. As they are clearly meant to be main characters. Yet, what about some of the side characters? What is gonna happen with Sun? When the other girls like Diane get more spot light, and the nun, otaku, tomboy, what will happen to Sun as you start needing to spend more time on other characters? Sure you can take the incest threesom route with sun and her sister, but arent yvonne and her cousin, and Maddies workout partner and her sister also clearly heading in that direction?
For the girls the MC lives with, I feel like you would actively have to try and forget about them, but for others, mainly side characters, plus having no conflict? What future could the theoretically have?
