It goes like this:

Castle1 -> Castle1N -> Carrot1 -> Carrot1N -> Labrat1 -> Labrat2 -> Colon1 -> Colon2 -> Psych1 -> Psych2 -> Beach1 -> Beach2 -> Diam1 -> Diam3 -> Tube1 -> Tube2 -> Medivo1 -> Medivo2 -> Jung1 -> Jung2 -> Hell1 -> Hell2 -> Damn1 -> Damn2.

Shareware Demo levels go like Share1 -> Share2 -> Share3, and the HH98 levels like Xmas 1 -> Xmas2 -> Xmas3.

Don't forget to make Labrat3 harder too =(!

Admins, don't own me for bypassing the filter and better remove (-) from the filter. It isn't such a bad word anyway, and it's causing problems when it comes to discuss the filenames.
