How do you beat level 3 on casuality on bored.com

move the light onto the guy by the building across from the light and he tries to go and hide. The can rolls over into a cars way and then he changes direction. When the guy who is hiding goes by the cans, click on the top can and it falls over and kills him. then a car comes and skids to a stop.
When you kill the guy with the can, the car drives in. Shut off the light when the car passes through, and it explodes. The guy by the tower goes to see what happened. Don't let him. Just then, someone else comes around the corner. Click the gun in his hand and watchtower-leaner goes to him instead. Click the boxes and knock them over. The new stick guy freaks out and throws a bomb at the watchtower, killing all. And then the game is beat.
