Well, even if it doesn't use the Oblivion trick, I still consider it an Oblivion level.
And...what happened to the level design of Castle of Oblivion? Where is the word "OBLIVION?"
I've been thinking of an idea: To make Version 4 of Lemmings Racers, which includes streetlights and retarded chickens, and real-life cars. Also, there's an oil slick which makes the lemmings slip.
