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 ]
