Extra points and get smaller: If you bite the very tip of the snake tail
you will get 500 points and also get smaller.
Keep points and get smaller: When a level gets too hard to complete, play
until you are at zero life. When you bite yourself, close the game before
your tail hits your head then open it back up. You will find that you
still have your points and the snake will be very small. Note: This will
only work when your life is at zero.
