For a first Quake map it's really beautiful and highly detailed. Most importantly, it's fun. I loved the floor grates etc. Quick little map on the easy side, nice usage of the progs. I believe yours is the first single release using progs_dump.(?) There have been two jams already but this is how I intended the devkit to be used. So thanks for trying it out and congrats on the results!
If you are planning to revise this, my only suggestion is the ammo balance is a bit off. There are sections where I ran out of ammo but I am a pretty terrible player.
Here's a demo that should be compatible with Quakespasm.
