Appreciate the feedback! We did originally want to implement a more solid gameplay loop - having a quota for the day, being able to open and close the store to stop customers coming, having something to upgrade in the kitchen, and being able to experiment with more than just soup - something just as systematic as the rest of the game right now; like using a meat and a binding agent to make a meatball, which could be flattened into a burger patty or something.
Even pasta makers to make spaghetti out of anything, a blender to make smoothies, a frying pan and a deep fryer - and having customers leave if they're waiting too long (or just penalize the player with a smaller tip) - all things we considered, but cut for the sake of scoping the game properly for the jam. There's plenty more we can add to give the game more purpose, so I'd love to hear what you'd think would help make things work!
