I'm so for n00b's idea, even though I didn't get half of what he was babbling.

And because I can, I'm going to tell you about the wonders of level names, Joe-Bob.
You see, making levels is an art. Most paintings and drawings and the like also get names, at least the ones with meaning. The same goes for books. And all the like that you need creativity for.
So, a level name can either be absolutely and totally unrelevant, and you might just as well call your lava level "Lava is hot" or something, but a really brilliant level needs a brilliant name that adds to the mood of the level just like music does. That's why people love stories like Steven King's "It". Because it isn't called "Horror Story About Some Monster".
