Call it DM8.5 (1/2 of DM17), this map doesn't add anything good to the concept of DM17. It's an interesting retake, but the swallowing esophagus tubes just didn't fit in here, and they weren't well placed either, as I could often see the ends of them when they bulged out beyond the walls they were supposed to be connected/confined to. And what's going on with the tubes in the green-lighted area? That just doesn't look right.
And one last thing- this map would probably look 5 times better if it wasn't at 100% brightness. Fullbright is one of the biggest turnoffs in my opinion.
