Cute, a little stressful though haha. Could use a few features:
-Small timer (could be a countdown, clock/stopwatch, or just an hourglass that slowly runs out of color) above the customer's head when they get to the register
-Ways to use money, maybe you could make things like perks (example: customer can wait longer, you get longer days, cooking time shortens/time before cooked food goes burnt is longer, etc.) or decorative things, like color schemes, cafe themes, different colored appliances, paintings/other decor, etc.
-Somewhat customizable player, it would be nice if I could customize the lil guy I play as a bit, especially for those ppl that are darker toned, but, I do know that would take a lot of time and effort so take with a grain of salt :>

Thank you for this wonderful experience, to everyone that worked on this game <3
