- Far far away, somewhere in Oregon prairies there was a Snake! It loves apples, each of them adds five segments to the Snake, but be careful: if snake bites itself or hits the wall, it would die of dysentery! Become a mighty snake with 150 segments length and get level up. Good luck! Control snaky with cursor arrows. 'Space' to pause, 'N' for new game.
