Awesome experience! No doubt you are talented a lot. Visually it's great - the "details" like that you see a pyramid in the background while wandering in an otherwise unsignificant outdoor area, adds to the atmosphere. And the music specially, it's great.
I like the textures, how they are rusty and look so good when used in the semi-darkness, which is frequent in the whole map.
Gameplay is fine, it's actually a Doom gameplay, even with the new monsters. It felt quite easy compared to BoR 1, at least early on - I first time died after the yellow door. You see, I always happen to die a lot, mostly from trivial mistakes. But the difficulty of this map was comfortable with me, there were no unfair archvile or cyberdemon encounters often used in maps nowadays to spice things up. I felt satisfied when I was able to relatively easily blow up even the bosses. (I didn't even let the final spider shoot very much, but I did notice his arsenal was deadly, apparently even a BFG!)
The only thing that I wasn't keen on were the switches. They have the same problem as switches in BoR 1: They're often very easy to overlook, or you don't even recognize them as switches. The worst is the switch that raises yellow-marked bars, I wandered around the whole map before I found out I have to press that wall. Other trouble were three switches in the soulsphere pyramid, as I found one, swtiched it, and only by luck I later returned to the pyramid and found the other two. Maybe it's just that I don't know Hexen or the game where they were taken from. Anyway I would have appreciated if switches had borders (silver, gold or other) and/or were a little highlighted.
But overall I enjoyed a lot, and switches aren't enough of a reason to not give 5 stars rating, since it just looks and plays that great. Good job.
Will there be new titlepic?
