How do you pass level one on casuality?

Answer 1

There will be a guy who walks into the elevator at the beginning of the game. Let him go up to the second floor and talk to the guy at the desk. While he is standing there, click on him, and he will slip and make a lot of papers fall off the desk. Then he will walk back to the elevator. After he goes back down, click on the picture hanging on the wall on the second floor. The guy at the desk will stand up to go fix it. He'll slip on the papers and hit his head on the desk.
Thats how he dies. :]
