Wow, that's quite a lengthy report. Thank you for sharing your opinion. I'll look for ways to make the breast size of dolls adjustable so smaller sizes will be possible even after leveling up.
However, I can't make promises with the customizable breast size for others, such as the NPCs. (And the mix of SFW/NSFW artworks. People had mentioned this as well, but I'm having a hard time implementing this for now)
