So first of all, in case you didn't read my bit on obake's level, I'm not really a fan of coloured lighting. It can look OK in places but I prefer it used subtly, as opposed to the solid colours going on here. I know that that has some precedent in PSX Doom (which I don't really have any experience with), so you can ignore this completely if you want. But I feel like the really extreme solid colours remove a lot of the visual depth that can come from normal light and texture use, and just look a bit ugly to boot. The fact that you've got some pretty hard edges for some light sections, like the blue patches in the sewers and the red square in a hallway, doesn't really help any and I think things like that would be better with rounder shapes and/or at some in-between light levels.
The exception to all that was the disco pit in the end, which looked quite funny and worked well. The outer silver area being normally lit made the centre lights stand out all the more. On the other hand that area and the surrounding rooms had some really flat texturing and lighting, the solid colour blocks looked a bit odd especially since other parts of the level had a lot more detail. I really liked the look of the outdoor zone, and the starting room with the pipes was nice.
The use of grates with hallways or buildings behind them worked really well here, and really gives the level a sense of being part of a larger area. It's also a little deceptive since the level is actually pretty short, I was fairly surprised when I came to the exit. Some buildings outside the window in the starting area would work well and fit with the aesthetic of being in a place larger than just a small Doom map.
The only other visual thing that bothered me is the switches for the lift at the start, you've got one going down the whole wall which looks pretty amateurish, and weird since the other two switches are indented.
For gameplay it was decent if simple in a lot of places. The starting room is a bit dickish and random, it killed me quickly the first time but since it's at the start it's not too bad.
Sewers are fun and kind of tough, a lot of the enemies take each other out but in instigating infighting the hitscanners, even the zombiemen, did a surprising amount of damage to me. The AV use here is awesome, a nice bit of panic without actually being too tough since you do have some cover and he's not likely to raise anything too deadly. Really liked it. I was surprised that the slime did no damage, I think you could've made it 5% just to put a little more pressure on.
After that nothing is too tricky, the disco pit clears itself out pretty easily and anything left alive can't hit you very well if you're far enough away from the edge. The enemies along the sidelines would be hard but you can basically just run around the side to the other room, and then run back to the outdoor area. The 2nd AV will raise a bunch of barons but they're pretty harmless, and even if you go for max kills you can pick them off pretty safely and let infighting do a lot of work between the mancubuses and the revenants.
All in all it's a bit uneven and some things don't do much for me, but nothing really annoys me too much and there are some really good parts.
edit: Funny coincidence that the three requests I've gotten are from the people who used coloured lights, when I don't really like them! :p
