Walkthroughs for custom maps.

I'm curious to know what the map author thinks about this. Since he created such a puzzle on his map, he probably knows how it works (but that's not certain).

Has the map author ever revealed his secrets to anyone in the last ~10 years? :) I saw some messages from him somewhere in a discussion, but they were very old and related to an equally old version (1.4 or 1.6). I only remember that he said he thought the version could be completed in 5 months.
