A puzzle focused wad that also contains action? Sign me up! That was close to my initial thoughts upon reading this file description. What this wad actually offers is long corridors and square rooms populated with enemies that are required to infight. That is the puzzle in every one of the five levels. How to cause infighting. This is more of a slaughter-lite level set than an actual puzzle wad so change your expectations accordingly.
Not canonically beauty from layout and some monster placement, but this map was a big fun for me! A level with some pretty mesmerizing places like the starting point, the raising pits, the really abstract techbase feel, the room lighting up a little when the player crosses some hidden lines in the mazes, the weird "theater" room that reminded me of Icon of Sin for some reason, the overall spooky feel, the final throne room... Great stuff.
Things i've kind of disliked are the maze section (especially the skull walls one), some lift that doesn't work (the one where the... blue skull key is iirc and the one that leads to the red door) and the switch puzzle is pretty dull to understand, at least for me... the one with the numbers in the sector, then after one day i get that the numbers are correct order to solve the puzzle lol. Also that horrible teleport maze-like room after the yellow key, damn!
Also, this map doesn't screw you around with the difficulty, as the previous reviewer commented this map can be compared to Deus Vult in that terms of difficulty and epic exploration, really. Just a raw 1996 version of it, but the comparison is all here imo.
Overall, a big and fun map to play for me. Cool stuff
