Adds dynamic winter - summer cycles with a moving cold snow front that gradually freezes and thaws the map. Turns natural bodies of water into ice and back. And a Christmas tree as a bonus :)
The map takes 8 hours to traverse by foot, so the wave can't really start at the edge of the map or it would take forever. I'm asking because I'm curious.
The snow front moves at roughly walking speed. So in your case, it would take around 8 hours to cross the map horizontally.
The season durations must be long enough for this. If there is not enough time, the snow front will stop, and a reverse front will start moving back from the right edge of the map.
