I've been playing this game a fair bit the past couple weeks and been enjoying it a good deal and hope there will be some extra character options/visualizations in the future.
Like, example, if you chose to have GG-cup breast, then unlock the Extra Milk perk, you'll see a change when you go to "GG+", but if you have Mega Milk (and presumably Gigga Milk, I haven't unlocked yet), there's no visible change for going 2, 3, or 4 cups beyond GG.
Will there be an ultrasound scene that'll let you check on your developing pregnancy? Maybe check what sex the baby will be or if you're having more than one?
And this is my "bigger is better" side taking over, but how about overweight characters? Or the ability to choose breasts larger than GG or a dick bigger than 50cm?
