		# Make this larger to make the game easier.

		# Smaller values make you glide slower.

# options depending on how your system is set up.  The basic requirements is
# a copy of ncurses that that supports "wide" characters.  That could be
# called -lcurses, -lncurses or -lncurses, depending on how it was installed.
# it also might have been installed in a subdirectory and needs to be found
# with a different include and/or library path.
