Perhaps it's just the end level teleporters, but I couldn't help but get a slight plutonia vibe from this one.
I think your tricks and traps level was the weakest link for me, but that's just because that sort of thing isn't really my cup of tea. Having the "lol jumpscare" as a trap felt a little excessive, and I think being teleported to a room that instantly crushes you might be a little more succinct. However, I felt the reuse of previous rooms was interesting. It almost felt like we were teleporting back through the previous parts of the facility we had explored, which I thought was pretty cool conceptually.
Besides the instant death room of archviles, this was very enjoyable. It felt like it was just the right length. I loved the room (I think it was map 06 or 07) where you had to find the 3 switches to open the door to the next area. While not entirely reinventing the wheel, it was a fun thing to do, both mechanically and architecturally, using half the switch texture to make it look like it was just the lever. That was the first time I'd seen that.
I also thought map 10 had a very interesting idea of returning to the final area from Knee Deep in the Dead, with the original portal Doom Guy took being shattered and the lake of lava being almost dried up.
In short: This was a very strong wad. Nice job
