Multi Player Snake Game Made in 30 Minutes!

This game is simple, but maybe someone else can enhance it. ;-)
In this multi player version of snake, the two snakes are controlled by the joystick. (I only have one good joystick, so I configured the two analog pads to each control a snake; you will probably need to reconfigure the controls, anyway. Tongue

)
The snakes can go over their own trails, but not the trails of the other players.
This game can easily be expanded to support 3 or 4 players if you have the hardware. ;-)
