Pyzzle is a free and open source cross platform Myst/Riven interface style game engine.
Pyzzle is written by Andrew Jones for the 'MadTV' project using Pygame library.
Pyzzle comes with Orbis Tertius test graphics. A small environment created by malefico which demonstrates Pyzzle's important features.

My goal for Pyzzle when it reaches 1.0 is to give its users the ability to implement large or small scale projects with maximum freedom and minimum hack work. Pyzzle game makers will have the ability to implement any features (and more) found in Riven.
