So far I've completed the White Wool and Yellow Wool, and it is a pretty fun map so far.One suggestion, you should make the asteroid belt circle all the way around, instead of only being in the general direction of the planets, to give it a more encircled/enclosed feel.
I was thinking about that, but the i would also have to have the planets in orbit, and that would make the map too large.
You wouldn't need to move the planets, just add more asteroids.
I think it would look a bit weird, because the asteroid belt would be all the way around the sun but the planets are in a line. If you have an idea for making the transition smoother, that's great and i would use it, but i cant have them all the way around.
