Neat idea! if you wanted to take this project further i think theres somethings that could be really improved upon.
Maybe have pans on-top of the stove to separate 4 diffrent cooking areas. Or maybe you could upgrade over time to add more pans. Its a bit weird being able to cook multiple things at once but having all the objects being placed in the center.
And maybe being able to push a Key that has a cooking menu to pop up to show you which food combos make the food people want to eat.
Super fun tho! also what did the green mean? i was a bit confused on that part.
