Makefile

# Example of a makefile to bulk export aseprite art onto a game.
# For windows, it is necessary to install some version of make such as:
# http://gnuwin32.sourceforge.net/packages/make.htm
#
# Details and specialized use of make are beyond this example. That's
# a whole different can of worms... Here I'm using the most simple of
# simples but any experts looking at this are welcome to improve.



# This assumes that all the pics are placed within this folder. Subfolders for each pic can be used but this was
# a game jam game so I just placed everything in the same folder.
