Doodle Defense is a cool concept that could use just an ounce more of TLC.

DD tries to span both the computer monitor and the projector with a single window, though Mac OS no longer supports that sort of thing. It should really be updated to support two windows: one for settings, and one for the projection. http://blog.openframeworks.cc/post/133404337264/op...

DD also doesn't seem to work with my webcam. So I cant figure out how to play the game.

DD is also built in openframeworks, a multi-platform framework, but was only released on MacOS. How come? I don't know. Porting to Windows and Linux would be easy and should be done.
