This is a great map, especially considering how much time it was made in! Short, but very enjoyable.
I recorded my playthrough of this map, and you can watch it here: https://www.youtube.com/watch?v=q-lBdiGspwo
An impressively large and labyrinthine map, even by 2018 standards. It was enjoyable for the most part, with reasonable health and ammo balance, and interesting to explore. My one big complaint is the teleporters - the map would have already been difficult enough to navigate without apparently patternless teleporters all throughout the map!

An amazing hellbase style level mixed with a bit of cave exploring, utilizes ZDoom effects to create a nice atmospheric environment to play in. I played on UV and found the difficulty to be fair while still presenting a challenge in a few spots. Overall it's pretty good but could of ended a little better as I am not a fan of arena endings.
