Monty Hall

In my free time I started exploring HTML5 Canvas and kineticjs, and for some reason I switched to Pygame module to write game.
While exploring Pygame I did't find sufficient tutorial which talks about basic required functionality as one available for HTML5 Canvas by Eric Rowell. So decide to write basic one by myself.

This game app is part of Pygame tutorial and Pygame porting to Andorid.

Code is open and hosted here:
