This game hit me right in my "Diner Dash" nostalgia. I had a lot of fun playing it until a customer got stuck on a table and couldn't leave. I think placing a customer at the table next to the trash can with fully upgraded table quantity can soft-lock the game. It was also pretty annoying to watch the character occasionally run in a little circle when arriving at a destination, wasting a bit of time.
The art is so charming, and I love the way all the characters bounce in place. I would recommend adding a way to see the customer's mood change so you can tell who is getting ready to leave. It would also be nice if customers formed a line instead of standing in the same spot, overlapping on top of each other.
This was a super cool entry, and I had a lot of fun playing it! By the way, what are those food items served at the restaurant?
