This is the classic snake game. A snake made of 5 small squares circulate within the image. You drive it by using the arrow keys. Regularly, small red squares appear. If you go over it with the snake, it "eats" these and become longer of one more square each time. As time goes by, the snake becomes longer and you shall ensure that it moves further, because if you stuck it, it dies and it ends the game. There are several levels of difficulty. Have fun with it.
