What to say...

Aesthetically, this map is really really nice. Everything looks gritty and dirty like it's covered in coal or dust. All the little effects, like the haze from the spilled blue liquid, the teleporter lightning, the little panel that tells you where the teleporting PaP machine is. It really felt like I was running around an official map because of the sheer level of detail and love put into the map.
The Wonder Weapon, the Atomwaffe, was really cool. It felt like a Blundergat had a baby with a Thundergun. It felt strong even in the higher rounds, and actually getting it wasn't an exercise in wild goose chasing.

Gameplay wise... oh lord. First up, you want to have a spawn rush mini-event like the beginning of moon, don't give me only three feet of room to work with. The spawn room is constricting and tight to the point where I seriously doubt it's possible to reach the 50 second reward legitimately. It's far too small, particuarly around the gardenbed with the tree around it.
Secondly, what the ♥♥♥♥ is wrong with you, being so unsubtle in teasing PhD Flopper? The Vulture-Aid tease is funny, but PhD is just a huge kick in the nuts. Without PhD, all of the explosive weapons and PaP variants becomes non-viable, and the Ray-Gun become a suicide wish. Not to mention those little rolling things in the boss fight would actually be bearable if we had PhD. A perk limit is a bit annoying too, but I guess I can understand that one...
The box felt really kinda strange. I kept seeing the Ray Guns and the Thundergun and Blundergat inside it, but I must have spun at least 30K away trying to get one of the latter two, to no avail. I got the auto luger pistol a ton, though, which was really appreciated.
The final boss fight. I felt like I was playing Blood of the Dead again, where the final boss is just a big Brutus. Having to fight the Panzerhund in the map was kinda fun, though it moved so fast you were required to get Stamin-Up, which is no fun. The final boss fight was a ♥♥♥♥♥♥♥ nightmare. Zombies spawning infinitely, those annoying little rotorbombs, Keepers as far as the eye can see, and the Panzerhund, looking like the exact same one we've fought the whole map, but strangely invulnerable to everything aside from the death ray, which felt like it took my entire waking lifetime to charge. Why make the death ray take so long to charge while also requiring you to fire it 5 times? What's the point of that?

All in all, this map was really beautiful, and I enjoyed my time running around it and completing the easter egg, but several parts of the map just feel like they were made the way they were for no other reason but to be dickish. PhD being teased was the most annoying thing I've seen in quite a few custom maps, and while the final boss kept me on my toes, it very quickly became tedious.
