This is an okay game. What might turn some people off to it is that you have to control just about every single thing; most games such as this are only worried about the food, drinks, and condiments if need be. However, you have to make each individual food item, and worry about plate color. The trash bin is also in an awkward position, too. It's a difficulty that most wouldn't bother with. :/ If the people had more patience, and the items didn't have to be made separately, it would be an even better game.
Well, it's taken me quite a bit, but I finally got to the 13th level. Failed, though. XD
My strategy, if it helps, is to find a nexus--a place where the people converge and then blast 'em! It's better to do it near the cars; after that, spend money more towards the virus spread and collecting money--go for the damage resistant and lifespan as primary strengtheners. Speed, infection chance and everything can come later.
