If you're wondering what the world records are and/or where to find videos of fast runs, look here:

http://www.vortiginous.com/snapdragon/ (the KD videos are near the bottom)

These are all vidoes made by somebody going by the name of Snapdragon. So far, he has made runs of MAS 1-6, and as far as I know, they are all the current records. They are being made for the Speed Demos Archive website. You can find discussion of these runs in this thread (which is actually what brought me to these boards).

There used to be a site called Cyberscore, which kept track of records for many games. It had a section for KD, with categories for size, speed, and numbers of objects. Snapdragon used this site for comparison. Unfortunately, The site isn't around anymore. I do remember that site listing the record for Make the Moon at about 11:34 (I think).
He's using these forums for comparison now.

It's so weird...just watched snapdragon's run through MAS4...it's the exact same route I did at first almost to a T, but somehow he's got about 25 seconds on me, without any charge & rolls! So weird...

UPDATE: He now has videos for all of the levels up, although some of them aren't record-holders anymore. His time for Make the Moon is six minutes and twenty-six seconds! :applause Wow.

I was waiting for the MTM vid...at least it's the last one :)
