Desktop Tower Defense

A live action puzzle game written for fun in flash. You have to stop your enemies, or 'creeps', from travelling all the way across the screen. Tower pieces can be purchased and placed on the map to kill the creeps before they make it across. Inspired by a Warcraft 3 tower defense map called Autumn Crossing and a few other TD Warcraft III maps. (Link)
