Use mouse to control the shark. If the shark eats orange fish, you'll get 10 points and your shark will be bigger. If the shark eats yellow fish, your HP will decrease and your shark will be smaller. But if you eat blue fish, your HP will increase. If your HP is 0, game over. It's easier because it has more orange and blue fish. Also your HP is 8.
