Does exactly what is promised. Good, fair execution of a potentially annoying theme. Nice styles too.

it says "bad request". 

d/l link works fine for me 

It wasn't announced here, sadly. Would love to join. 

This jam was announced by Sock on twitter on Sunday. I think it's a good idea to repost such announcements in GA next time. 

Nice little maps !

I much prefer sock's map, because of its "out of this world" architecture. Pulsar's map is much harder to do, and the geometry is too simple for my taste (too "square").

I activated the secret in sock's map, but wasn't able to find its entrance.

Also, dropping just a few monsters in there would be fun too (depending on the difficulty setting). Easy : no monster at all. Nightmare : well, nightmare number of monsters with Texan style action ! ;-)

Just a small crittic : the small disks floating inside the arches are too crude for my taste. They feel so "unrealistic" or so "old computer game", I think it would be better to make them differently, or adding more polygons to them, so they look like round instead of this crude "supposed to be round" shape. They don't feel "quacky". 

How do I keep missing out on all these map jams?

Looks interesting, will have to try them later. 

Sock's general procedure with map jams is to announce and organise them as secretively as possible, to prevent any people actually entering ;)
