This session could (& would) be entered & exited several times, although doing just a...

Please be gentle. I'm a pygame n00b and haven't touched pygame in years. This is my unique implementation of the classic game snake. In this game, the snake has a velocity which can vary along both axes of motion in increments of one pixel per frame and the tail follows the exact path the head tr...
