Classical snake concept with relative non-perpendicular movement angle.
First "game" I wrote in python several years ago, trying to learn pygame/python and solving problems as eg. how to implement mentioned "relative movement" concept.
Never got out of alpha-stage. So there isn't any thorough gameplay.
would've to-do list:
*speed up module geom.py and/or implement other solution
*rethink/rewrite gameplay elements
*improve control mechanics
*refactoring (menu code!, exec()!)
