Looks like the folks who play work on PopFly have released an alpha version of an online tool for creating web-based games.
Apparently, the PopFly Game Creator has over 15 pre-built game templates for you to try, hundreds of images, animations, backgrounds, and sounds for you to use in the games you create, and a way for you to write code if you reach the limits of what the user interface can do for you.
There are quite a few videos and how-to's already created to help you tweak existing games or create your first online game using PopFly Game Creator.
