This is the first real Python project ive persued that was of any significance. and i finally finished it

Made with blender 2.49b.
If there are any experienced programmers with any advice on how to streamline/optimize my code or any opinions at all i would greatly appreciate it.
this script uses game objects as nodes, not mesh data. as long as you put the node objects 2 spaces apart from each other the sphere will be able to find its way through any maze/series of obstacles.
btw, is there a way to upload a blend directly into my post? or do i have to use a file hosting site?
sorry for the double post but it wouldnt let me edit my first one
