# 	Actual game demo version is 0.0.4 but I am calling this Version 9.0c_September_2011
#	This game demo was designed and written by Kristian Naugle
#	This Danger From Above game demo was began on September 22nd 2011 and is my first attempt at writing anything in the Python programming language and to develop games using Pygame.
