A pretty chill game! The UI looks pretty good and the game has a pretty simple concept. I would like to add some suggestions too:
- One thing I would suggest adding is an indicator that tells you that you actually got something from the truck. I sometimes went in a race against time trying to go back and forth from the truck to a table only to come to back to a customer empty-handed. Perhaps adding a small object placed over the waiter's plate could be a good way to tell if you got something out of the truck
- Perhaps when starting, I think the first table should be a bit more closer to the truck as it seems to be one of the tables that I began to pay less attention to over time, perhaps a way to have the tables be well spread out is by having the truck be at the center of the map and have the tables surround it to allow the player to pay more attention to every table.
