Space Snake 2000 is a variation of the classic Snake / Worm / Nibble game. Most different is the navigation, instead of the usually 90 degree turns you must rotate the snake in a complete circle to make a turn, which makes it more difficult and more fun.
It also include other features like:
Different levels, all with their own unique look, Highscore, different pickups like Bombs, Mines, Shields etc.
