I wont have any time to play e-mail shuffle this afternoon, so just in case my assumption is wrong, you can snatch up my speed map from this address:

Few notes: Four and a half hours of brush work, almost eight hours of vising. A few bugs. A couple of health packs fell out of the vis version, big bleh, there. However, I ran through the level twice and it was still only a mildly difficult challenge to beat. I also hate the underwater waterfall error too, but no time to fix. Enjoy.
