Really fun "metal & slime meets runic" marriage of themes in a very compact (but quite big! the "medium" descriptor here is honestly a misnomer) hub-y map with cool and distinct rooms.
Curious where 8~ of the secrets are as 10 secrets and 8 backpacks are not too hard to find once you understand the sensibilities behind their likely positions, i.e. in dark corners, button operated (sometimes timed) or the design philosophy of "if I can get there, there's probably some goodies lying around". With this in mind, the map knows how to be playful as well, especially in the descending lift sequence, do not want to spoil much about it beyond mentioning it.
I played this on Nightmare and Fiends REALLY feel at home here, the rooms are claustrophobic enough for them to be scary in combat once being ambushed, but enough room is given to the player to dodge everything else on screen, generally Ogres and Scrags with the odd Vore and Shambler that you're generally quite over equipped to deal with if you have explored around, either dispatching or tanking them while running from the aforementioned Fiend(s). It feels fair and never too hopeless, the amount of enemies for how much space and resources the player is given is balanced. Also this is subjective but the track from the recent music jam fits the vibe of this really well, an unwelcoming place with moving parts with ambushes around the corner, steady spooky beats to slay Shub-spawns to.
