Really interesting and fun mapset, Dante. I enjoyed the hell of out the first five levels, Memento Mori being a huge eyebrow-raiser. Your usage of traps and frequent slaughter armies are well balanced, requiring wit of the player and skill to subdue the demonic forces. I didn't find any bugs so far, playing with Complex Doom made things WAAY harder than they needed to be, just the way I like it. I made it to MAP05 before discontinuing gameplay. I don't know if it's Complex Doom, or Zandronum, but the massive framerate drop after the Lift Door Room killed my will to play it. I'll try loading without Complex here in a bit to see if it's better. If not, I do enjoy this set of levels. You put time and formula into the layouts, some even having a PSX Final Doom TNT feel, which is WICKED.
For fellow players, keep your wits about you. The level changes as you progress, so take note to these changes and they may save your life and countless restarts/save-loads
I don't have much of a critique, as I'm more of a reviewer than a critic who gripes about their play-style and how the PK3 doesn't suit their tastes. This is what I play Doom for, and if you're looking for a casual experience, Start with Hurt Me Plenty, or HNTR.
