Audio, art, the feels and juice are absolutely amazing and taken care with love!
Having a bit of tutorial/hand-holding would be nice, just a border around the pasta station would immediately tell the player to interact with it. Controls can be more intuitive: invert the drag control, and have a click for light-tackle would be great.
I realize I can stack multiple pasta before serving, which is nice; what's also nice is being able to just interact with the table and serve all customers.
I haven't found a way to know which customer pays or doesn't pay (maybe my game sense is bad), but I would love some more clarity on this. It would also make the trust theme pop off more.
Not killing anyone also shows the everyone dead screen which breaks the immersion.
