Yes, I did play it in dmsp.
I think the some of the lights look pretty good, for instance the ones on the very out edge on the metal, but the others are too concentrated. A really bright spot and then the rest of the area was really dark. Not very appealing. The exception here is the colored item spawn lights you used, which I think was cool. Also, it took me a long time to figure out that a teleport lead to the 'lava' rooms. The whole thing didn't seem to fit. The lava on the walls was a great idea though, and would seem to be a good idea for an entirely separate level.
3/5, but closer to 2.5 honestly.
