I've been trying to archive as many levels as I can. I have a link to a Google Drive folder with some levels (including all official ones) in the k2xl forum. I'm locked out of my forum account but will keep the Drive updated. If you have backups, feel free to contact me at davidspencer6174 at gmail
This is also my favorite level, it is also one of the levels that forces you to not follow one of the rules given during the first level of the original.
