Great first effort, Shambs. Late to the party, as per my custom, but I'm catching up.
While looking for the way to exit the first area (btw, the 3 sides rock door sucks big time) I accidentally broke the map, and I figured you'd find more interesting seeing how I did that than how I died in my first run through the intended route. So there goes:

Speed Demo

happy you finally came around to producing maps. 

Yeah I admit the rock entrance should have been made clearer. I completely underestimated the typical Quake player's determination to ignore persistently ignore an obvious "secret" entrance, marked in 3 different ways, in a small area with no other options, and instead contrive to steep slope climb which never appeared in any Id map nor any custom map as far as I know.... But I learnt my lesson, and also the wise words of negke: "The players are the worst thing about mapping" ;).

If you fancy a catch up.... https://teamshambler.blogspot.com/2019/05/mapping-portfolio.html some may have proper running potential... 

...but I don't.

I've already done some catching up and I gotta say you've got some real mapping skills, mate. Gonna write something thread by thread. Maybe post a coupla demos, too.

As for the secret entrance, it's not that it wasn't obvious enough, but I personally did not like organic stuff as rocks moving like automated doors... I'd have preferred like a func_illusionary or sumthin'...
