Most difficult levels in existence?

[quiznos00]

Actually, add Dave Borgman too, he got a good stack in as well.

But what I'm really saying is that those 15-20 levels shouldn't be over-talked about.

Well, Dave Borgman really didn't contribute positively to the set...

And there were 13 levels that were to be in CCLP2, but didn't get in because the designers couldn't be contacted. They can be found at the bottom of this page under honorable mentions. Bowling appeared in CCLP3 anyway. And Pipe Dream would have been one of the best levels in CCLP2, had it made it in.
