The green feller is your snake.  He doesn't have a head, per se, but you figure that the direction that he's moving in is probably the direction in which his head lies.  The red squares are designated apples.  Your task is to eat them.  These are magic apples, so when you eat one, you get longer and faster.  Control lies in the use of the arrow keys.  Up, down, left, right only.  If the snake runs into an apple, this is eating it.  If it runs into itself, he dies.  Well, maybe he doesn't die, that's rather harsh, but he at least causes himself enough pain that the game discontinues.  The blues squares are wall.  The snake doesn't like ramming his head into that, either.

Press the new game button to start a new game.  Press the pause button to pause the game.  Press it again to unpause the game.  The gray rectangle beneath the play area is something of a status display.   However, for an apple count, check the bottom of your browser window.

MODES OF PLAY: You'll see beneath the gray rectangle is a button for choosing modes of play.

normal: Very simple mode, although once I figure out an efficient method of generating levels, it won't be as simple.  You have 10 apples to eat.  Eat them.  There will be one apple on the board at once.  Then the game ends.

endurance: The goal here is to eat as many apples as you can before dying.  I think my record here is something like 36.  Another apple will appear when you have eaten the last.

endurance 2: The goal here is also to eat as many apples as you can before dying.  The added dimension is that apples will come and go on the screen randomly.  I think got up to 76 on this one.
