The visuals are terrific, the game is really beautiful. The gameplay is ok although the moving camera effect isn't necessary imho and doesn't combine well with the lag I have on the web version.
I have somewhat of a questioning on your interpretation of the theme. It works for gameplay, but I'm a bit confused by the message it delivers : make people food you think they will like rather than what they ask for. It's not the behavior I would expect from my next-door fast food place to get something else than what I ordered, without my consent. Maybe a way to fix that would be to be able to suggest other dishes, based on what we learn about the characters (ideally with higher price, but also some we know we make them feel better, their favorite item, etc.). I think that would give the player a better role than trying to guess what the character want and being shouted at when just cooking the requested dish.
There is definitely some potential here, good job !
