Just wanted to give props to Anton Lapshin for developing Bart's Game, based on an idea by yours truly and conceived right here on the OpenGameArt Forums.  The basic idea is that it's an arcade/puzzle game in which there's a human in a maze inhabited by monsters.  The catch is that you don't control the human at all (who is constantly freaked out and running in random directions) and instead you move the walls of the maze to corral the human toward the exit while preventing the monsters from catching him.  Check it out!

Please note that, while it works in its current form, it's still under heavy development.

Peace,
Bart
