Like the concept and the art!
It felt like I was doing something wrong the whole time, like it felt like I was meant to please everyone at the same time, but I couldn't. I think it could've worked better if instead you had to put the food on the conveyor yourself, keeping in mind the customer order and if they might leave etc. Some sound or animation would be nice too.
But for a first game this is really cute and well done for getting something uploaded in time!
