I wonder if anyone is familiar with the version that holds the old Concrete World, since I'd love to show it off on YouTube so someone can actually see how it used to be like.
If you do seem to know, let me know as well so I can begin doing things. I'd also like to have a download link of the said version, if you do indeed find it.
The explorer shows that the first version it was added in is 0.067, so I'd go to the archive page and download from there.
