Interesting map that one, very weird how the creeper works though.
J is there something coded into the script to give that world some kind of super gravity that makes the creeper flow how it does? Or was it tied to the roving emitters that were around the edge of the map?
I changed the creeper flow rate and evaporation limit so that a thin layer of creeper spreads very fast. The emitters around the edges don't have anything to do with that. You can remove them by powering all totems.
I suspected it had to be something like that when i noticed berthas and mortars both really do jack on that map at points.
Either way, nifty map too, makes me wonder what other tricks you can pull with the creeper on custom made maps.
