Dave Borgman
Dave Borgman is a somewhat famous level designer, having 21 of his levels appear in CCLP2. He has made two custom level sets, DaveB1 with 65 levels and DaveB2 with 23 levels. They are also among the oldest, being last updated October 23, 1999 and November 14, 1999, respectively.
Dave's levels, much to the dismay of the beginner chipsters, often contain a large amount of guesswork and hidden information, usually via invalid tiles. Chip Search, Tricks, The Search for the Exit, The Block Stops Here, Block Away!, Blocked Trap are all levels that appeared in CCLP2 and all levels that he designed. He also designed the CCLP2 level A Sample of Things to Come, which in his level set was the first level and did indeed provide an accurate depiction of his later levels, but didn't fit well in depicting the later levels of CCLP2. Most of his other levels are simple in nature, often involving many monsters with some puzzles here and there.
While he has been successful designing levels, his CC1 and CCLP2 scores remain unknown.
