There should be some time pressure to give some challenge but it should definitely be possible, so unsure if the version you got locally didn't work properly. The first customer that wants said pizza waiter is carrying will grab it from the stack, so it's also possible the customer who ordered first didn't get their pizza because an earlier customer got it. As people mentioned before, orders above head could have made this clearer and that's definitely an upgrade I could do. In any case, the pizza creating and recipes could use some refining but I'm glad I got as far as I did during the game jam.
No worry about harsh critique! I appreciate any critique as long as it's valid!
