Walk around with the arrow keys! The signs will give you most of the instructions, but just in case you miss any of them, then: Click on either player 1 or 2 to change how they look. 1- turns on 1-player mode 2- turns on 2-player mode and teleports the 2nd player to you. A,W,S,D- used to move the 2nd player. T- talk to any sprite your player is touching, including signs. M- the radio man will explain this one ;)
