This is a very moody game. The art style is very cute and the sound effects and music are also nice.
An in-game recipe guide would be nice. I needed it to have the tutorial image in the corner while playing.
I found the customers to be very impatient, and it was a bit frustrating that serving them felt like an impossible task at the very beginning. I would suggest that a gradually increasing challenge could be built into it.
The outcome of your work on this was exemplary. Well done!
