Good job! It looked good and it sounded good. I feel the restricted color palette wasn't the best choice for this game though, especially once you start buying more ingredients. It becomes harder to tell what everything is at a glance. Same with customers being the same, its hard to tell who ordered what.
On the topic of more ingredients, i really liked the mechanic of buying more ingredients as you go! It puts the difficulty in the players hands, and reigns in overzealous players. The better and faster you are at pizza making, the harder it gets.
What I think really sold everything for me was during my first run when the Only order I got the entire day was " a cheese pizza, with pepperoni, without cheese." And I swear it was the same guy!! Just coming back over and over again so he can shove another saucey sausage pizza down his throat.
