The player controls a red headed snake, which roams around the board picking up green apples. By eating, the snake grows in length.
Use 'w', 's', 'a', 'd', or touch inside the canvas to move the snake.
It's GAME OVER if the snake run into its own tail.
Hitting the border doesn't lose you the game: the snake will simply reappear on the other side!
In "normal" mode, the snake's speed increase after eating an apple; in "relax" mode speed is constant.
