For first time I played this level as secret level e3m9 of Episod09 (Again Hell) compilation, widely known as Wadpack2 by Gary Karnik. The level is scored three plus and half too and besides really deserved such estimation. Furthermore k9 is very playable, UV skill is somewhat tough by today standard certainly. 70% secrets are maximum here. Three sectors are too thin to be counted by doom.exe. But I've visited all them. I've checked demo with Eternity's walkcam and found no lost souls. Here is my recommendation. Watch wad's internal demos. They are pretty fast for that time. 
Trap in red key's room works properly only under 1.2 engine. But it makes map only funny to play
