Last night I finally released the 0.2.0 version on the pygame website. This is not the release I originally planned (no "The South Bridge" level for now, and now story line) but is an important release! The pathfinding module is ready (maybe a little buggy right now, but works)! So... you will play again the the same 2 levels of the last releases, but the game engine is more mature right now!
From this release, I added dependencies to other modules I released on Pypi... read the documentation in the pygame page.
