The game has some sounds but not quite a lot where the settings for them would affect them.(i tried listening to the game with headphones)
eating makes your character fatter and I believe it's also a slight decrease in drunkenness.
Idk if the game punishes you later for getting pretty because that's what I did to wait. Work until she could afford a few clothing pieces and then the dude comes in.
(I've made it all the way to haven and out and the game never gave me a penalty for doing that)
