A couple of levels done a long time ago (end of 2009-2010) MAP01 was used in First-Try Demo Contest #8 at 01.06.2012 (beat an unknown map which will be posted at specified time for all participants as fast as possible, sending demo file as a proof). All demos from the contest are in "fdc8demo" subdirectory. MAP02 has been done earlier and uses only original IWAD textures.
