You must excuse me for writing "Jumping is cheating, you know!" for my wads, because I made these levels between 1995-1999 for vanilla DOOM and by 2002 that I was uploading them here, jumping was being implemented in the source ports, and was considered to be cheating.
And because of my shortsightedness I could not predict that it would become "a very important part of the game" in later years, and people would judge me without looking at the time of the wads.
My mistake.
By the way, a great wad, I know. ;)
P.S. Who knows, I might even consider coming back to DOOM editing and make wads with jumping in their core game-play.
