The Land of the Livid Dead is an awesome level, with enchanting musics and strange fantastic design, it's my favorite level. I do like the longest shortcut too, it's a short and quite challenging level. But I don't like the Knaaren's desert at all.
I think it's a good level, I like the mood very much.
I also like the snow level, I do not remember of his name anymore. Oh, yes : le sommet d'outre-nuées! Without the end of the level, it's annoying!
The level supmachin is talking about is SBTC
Well, I have had fun in the Knaaren's Desert, so I like it... but the Longest Shortcut is really annoying to me
