I'm far from being an expert in doom levels, but I really liked this WAD. Its atmosphere is astonishingly good: the monsters are really cool, weapons have a distinctive appearance and have a good feeling (the grenade-launcher is amazing ♥), and all the environments are gorgeous: gloomy forests and cemeteries, deep caverns, dismal manors, bleak mountains, … there is a really great Lovecraftian vibe everywhere, supported by a top notch sound design and music. Moreover, the monsters placement is top-notch, creating some credible scenery, like worshiping scenes in obscene cathedrals, insane invocations of grotesque creatures, … also, it's worth mentioning that the animation of the water cascades is astonishing!

In most of his stories, Lovecraft refers to impossible geometries, elusive angles, seemingly moving spaces, intricate Arabesques roused into a kind of ophidian animation, … and I was curious if this could be somehow implemented in zdoom. I don't want to spoil too much, but Womb (map10) has some horrible corridors, and Archive (map11) gave me the feeling that everything was constantly falling down.

Unfortunately, on the not-so-bright-side, the level-design is a bit simplistic, there is only a single ammo type, and you get powerful weapons quite early in the game, including the completely overpowered BFG-like, which makes the game super-easy, even on Ultra-Violence difficulty. The last boss is a huge disappointment, I was expecting something epic, and … well I don't want to spoil it, but … meh.

But everything else is pretty neat and if you like Lovecraft's universe, those 16 levels are completely worth 45 minutes of your life.
