I cleaned it up a little and added more to the main description, and replaced the old file with the current one. I tried uploading the 7z file and gave it a custom name, but this glitched the download (clicking the link opened a page of gibberish). I couldn't delete the file or replace the name, so I had to upload the zip instead. Maybe an admin can fix that. A lot of that description about submitting custom levels to a contest and treating Worlds like that's its main purpose seems rather undermining and irrelevant nowadays. Maybe that should be removed or rewritten?
