Click the green flag. Move your mouse around the screen and the diver will follow. Maneuver the diver around the octopi (the more points you score, the faster they move) and collect stars. When you touch a star you get 1 point. There is a high score. Try to beat it. Don't touch the octopi or the game ends. (You can tell me your high score in the comments along w/ your account name, so I can add you to the leaderboard.)
I got the code from a book written by Jon Woodcock. :)
