After the apocalypse, a little penguin opened a special restaurant, selling scarce supplies (such as toilet paper, drinking water, and canned food) to survivors. Simply tap the screen to help the penguin greet customers and hand out supplies; customers will pay with coins. Earned coins can be used to upgrade supplies (making canned food sell for higher prices, increasing drinking water storage), and also unlocking the number of employees, customers, and employee speed. As the restaurant grows, so do the customers, and watching the coins accumulate is incredibly satisfying – the sense of accomplishment from "making a small restaurant big" is truly therapeutic!
