this is my version of the popular snake game. The snake is controlled by the mouse so be careful when you start :) it grows infinitely long...you should download the apple.jpg file for the game, or graw one of your own just name it apple.jpg and place it in the same directory as the code itself :) have fun. If there are any problems please post a comment :)
CONTROLS>> left MB increase speed; right MB decrease speed; middle MB pouse game and resume aswell
