No man it's actually pretty easy to speedrun due to all the open space. You should try it. The monsters don't get in the way too much, in fact what gave me the idea to try was how I was able to run around the edge and through the moat pretty much unfettered.
Very nice, I'm sure I wouldn't be able to get that time - I have a habit of making maps that I just can't quite demo, either from lack of skills or lack of patience to play the same map more than 20 minutes without getting reckless. But anyway, reading your txt, how is rboom different from prboom? Besides not supporting extended nodes until map21, heh. And yeah I moved the arch-viles just to make it harder to kill them fast. But hey, you were still able to finish the map in under 2 minutes.
I used to be able - well, almost - to do the same thing with map13 for similar reasons, except if you're not fast enough it gets utterly flooded with monsters. Also, since now it needs all six keys, I'd actually have to go in some of the more cramped buildings. That's put a speedrun of the map beyond me.
As for rboom, I get asked about this occasionally, I should put up a web page or something... There's not like one obvious thing I could point to and say "that's it's unique feature". I mean PrBoom v2.3 was quite different itself, it had what is basically an old version of Eternity's console in it, for instance. But it was full of bugs and never really completed. What I've done to it is mostly code cleanup and bug fixes, and some interface tweaks to reduce annoyance. For example, since this is a demos thread, I can do "-complevel boom" instead of having to remember any magic numbers :)
Excellently done :) It's great how you could take my route and improve it within like an hour or so of my post, that shows how skilled you are I think.
Did an UV speed using your route in 1:52 - simply because no head bobbing freaks me out. :P
Anyway I'm pretty sure this thing could go to 1:45 or even 1:40 if the monsters cooperate with the player better.
- I was a bit surprised to see that you stayed quiet for that long. I think you had a bit of trouble from the first two archviles as a result.
- You skipped one of the teleporter lines! That's happened a lot to me but because it didn't happen yesterday I forgot to mention in my text file that I usually stop straferunning when approaching a teleporter.
- Interesting how you went up the mountain from the west, you seemed to get through the crowd around the exit a lot faster too.
BTW The reason I turn off bobbing: if you start firing a weapon when bobbing has moved it off centre, it kind of gets locked out of position until you stop. And this was somehow managing to throw my aim off :) That was years ago and since then I've just got used to feeling like I'm floating round maps on a hoverboard ;)
