Use the mouse to steer yourselves to the yellow fish to earn a point. If you eat a red fish, you lose all the points you had gained so far. Try to get the highest score possible. You can't exactly beat the game, so don't freak out that you have 500 points and the game hasn't ended. My high score is 17. Can you beat it?
I used a script from http://scratch.redware.com/ so all credit goes to them. Have fun! ☺
