Doodle Defense is a tower defense game that explores drawing as a means for game interaction and play. Players draw mazes and towers on a whiteboard with regular dry erase markers to stop projected foes. The game recently received 150% backing on Kickstarter is still being developed and improved. This project has been featured on IndieGames.com, Engadget, PC World, Ubergizmo, FastCo Design, UGO's list of the top video game Kickstarter projects and many other publications.
The game uses a camera and a projector in conjunction with the whiteboard to create a unique platform for play. The code and system is all my own, written in openFrameworks. The code is open source and can be viewed here.
