Possible world generation technique

     I commented some stuff and added in a way that I may use to
generate the world based on the map.
     If you think of the world as being made up of 8X8 chunks of pixels
I made the 4 pixels in the middle of green chunks green and the
entirety of blue chunks blue. If a green chunk is adjacent to a green
chunk they will create a “landline” connecting them and after
everything is connected the green and blue will spread out with the
green spreading at a much faster rate.
