Press the green flag. If your mouse isn't down, the blue fish chase you. If the mouse is down, the red fish chase you. The game starts with 2 fishes. After 5 seconds, another fish will appear. Colour choice is random. If your mouse is off the screen, you have three seconds to get it back in. You can't bring your mouse out of the screen more than 5 times.
