I saw this level for first time as boss level of Episod07 (Escape from Hell) compilation. The level scored three plus and half in the "OFFICIAL QUICK REFERENCE GUIDE FOR DOOM PWAD'S" and really deserved it. I like Greg Grimsby levels. IMO his E2l2_gg1 (tweaked e1m2) is one of the most impressive and one of the most "dissimilar" to id originals levels of pre-nodebuilders era. This demo is far from perfect. Again all lost souls were killed. May be route with plasmagun grab and straight route to exit are slightly faster, but you need more luck with insanely teleporting monsters.
