			You are Mr. Goldberg, a famous and well respected businessman.
			You're looking to expand your business to a new city.
			It looks promising, but has one serious problem - too many
			people living in it, getting in the way!
			Maybe if you build some factories near their homes they will
			eventually move out and stop bothering you?

			Instructions:
			 * earn money to build stuff
			 * pollution will cause people to move out
			 * you win when city population reaches 0!
			 * 1/2/3/4 to choose building, WASD to move, SPACE to build it, Q to quit

			                        [ any key to start ]
