For example I think the whole HUD where you play sex scene can be deleted, what I mean by that is to use areas on monitor in this case parts of the animation to have interactive areas, so you dont need to click to change what you want to do.
When I was playing I saw that breast and mouse have those "limits"
Adding physics would be nice I think.
I would explain it more properly in private cuz I dont want to compare games or animations
I wish you good day/night :D
