There really is just no enough time to do anything. You can complete most of the levels but by the time you get the orders for the second batch of people you're already out of time so you have to replay a level at least 3 times to memorize exactly what you need and make it ahead of time.

You don't get nearly enough time to finish the first level, the food spoils (Burns way too quick) and there's no pause. Not a very fun game at all.
