What is mean by this is that breasts, muscles, hips, ass, etc. grow independently of each other. For example, you could buy muscle serums, breasts growth serums, height serums, etc.
However, this would take a lot of time to implement (5 weeks or so). The problem is that if I want the game to have this, I need to go ahead and add it to the game, otherwise, it would probably be impractical to add later on in development.
If I decide to do this, I'll probably release a small update (v0.1.1) sometime this weekend, then skip straight ahead to the targeted growth update. This update would probably be released late July and be version 0.2
I've attached some images of what this might look like on the main character (Emma).
Let me know what you think. Thanks.
