Advanced controls (inputs)
Inspired by the Snake game in the old Nokia cellphones, This adds more advanced controls to the game: Diagonals and clock/couterclockwise
Diagonals
You can now control the snake using diagonal buttons (defaults are 1, 3, 9 and 7 on the numeric keypad).
This allows you to control the snake with only 2 keys! 3 and 7, or 1 and 9,
Eg: Using 3 and 7, by pressing 3, the snake will either go right, or down, depending on where it's facing. 7 will move either Left or up.
Same with 1 and 9. 1 will either go left or down, and 9 will either go right or up.
Clock / counterclockwise
This is pretty straightforward. By pressing Z, the snake will rotate counterclockwise, and by pressing X, clockwise. This also allows you to play the game using only two keys.
