I like that the food system is an optional part of the game; using it as a booster sounds fun. I'm always a little turned away by a mandatory food system, or a "hunger" system like some games have, but this looks really good and, just like the clothes system, i think this update is really going to enhance the way the game plays and the immersive quality of it. Really happy to see you go this way with it.
It would be cool to see this come into play with the family, like feeding the family oysters at dinner for a chance at a sexy scene, since oysters are an aphrodisiac. Not expecting anything obviously, just a thought that popped into my head.
