Thanks for responding to my lengthy comment.
In regards to the speed of progress in game, I do have one idea. Perhaps you could implement 3 settings - Fast Progress, Normal Progress, and Slow Progress. That way, users can select the rate at which the main character gains strength and charm. Additionally, I personally prefer particular character sizes that are below the max level 4, and I dislike that my character will continue to grow from that point when I don't want her to. It's a bit inconvenient to have to repeatedly go back to the SAD to make my character the size I want every time she levels up. You could add a simple feature to the SAD that halts all strength and charm progress, like a toggle switch of some kind.
