Most difficult levels in existence?

[pillowpc2001]

And because of that we got Exit Chip in CCLP2. Hooray!

Call me crazy, but I actually like Exit Chip. Although this might be more due to memories of first discovering/solving the level, plus the fact that I don't think I've even played it since 2002, back when invalid tiles were still cool...

To elaborate a bit on the memories - when I first discovered the level in EricS1 and read the hint (not present in the CCLP2 version) that read something like "There's no way you can possibly beat this level, but I can - muahahaha!" and after playing it for a while and finding that the obvious chips were booby-trapped, I actually thought the hint was serious (or at least the first half of it) and that Eric meant that the level was unsolvable... I'm not even sure if I figured it out it was solvable until CCLP2's release, at which point I realized it must be... Even with all the hidden items, it was still a good feeling to finally figure out the solution that I once thought didn't exist...
