Welcome to Snake
See that the LCD is on and press start to play
The snake is in the middle of the screen, move the analogue up, down, right, left to move the snake in those directions. Note that snake doesn't travel diagonally.
Move the snake to get as much food as possible, there is plenty of food as you will find out
Beware, snake will die if you run its head into the walls, or into its body
Take care to keep moving snake fast, its body will catch up with its head and cause it to die!!!!!!
Have fun, and get that snake as long as possible :)
