Rom Check Fail developer Farbs has unleashed on us all the Web-based communal adventure game creation game, Playpen.
The game presents you with a blocky point-and-click adventure interface; as you click around and explore, you will find your choices leading you down increasingly eccentric avenues — until suddenly you hit the edge of the world. Say you click on a path leading to a fountain, but there is no target page to the click. You are then dumped into a simple image editor, where you can paint the scene yourself and designate however many links you like, to however many other pages.
