From what i have seen, this is an amazing creation. However, I am unable to download it because I use a Mac. Do you think you could update this as a .sment file? If so, it would be greatly appreciated. Other than that one small thing, great job, it is an excellent build.
It's no Ringworld, but this is a great start! I hope some version of this makes it into the default build by Release time. What an easter-egg that would make! Ideally, I would like to see the default build get a modified planet entity that would allow this to have atmosphere & other planetary attributes.
