Just finished CCLP1 a couple of days ago. For the most part I liked it. A good beginners set and I have to especially make special mention to Andrew Menzies on his imaginative puzzles. I get the fact the puzzles are meant to be a first step for the novice of chips challenge, but in far too many cases the puzzles are a bit too easy. Chips Wikia has rated the difficulty well. One thing I was particularly impressed with was the emphasis on solving problems in the set, rather than ignominious dodging themed levels. Dodging is there, but done in such a way so as not to detract from flow of the game. All too often in the CCLP2&3 sets dodging becomes tiresome.
My favorite puzzle was level 124 Utter Clutter. Not quite a brain buster deluxe, but the solution is a slick polished one and has some devious pitfalls.
