Some of the game functions are just way too slow - ordering and giving pizzas to the customers needs to speed up. Pizzas burning because I have to watch a customer throw his arms up in the air is just silly. Could also use a set of mini oven timers as a thumbnail in non oven screens. Otherwise enjoyable but it's quickly become a grind.
Whip up a random level generator real quick so I can keep playing. Who cares if they become unbeatable - save the known beatable ones for the campaign progression.
