I gave it a solid go, the art and concept is great. In my first few attempts I had to go back to the main menu and read how to play until I finished a full shift.
I think a tutorial shift would be nice highlighting/guiding a normal workflow. Even a in game 'how to play' would be a plus honestly.
Another thing I think that could be helpful is when standing near one of the interactable elements, a "Press 'E' to use {object}" so the player can tell what they're interacting with.
Lastly, I think assembling the order is a bit clunky, honestly a drag and drop to the customers order to assemble would feel nice.
Anyways it seems like a fun project! Keep it up! :D
