A popular 'fun' (but uncompleted) glass map, that I was making about a year ago until some people stole it and put it out there as their own. I guess this wasn't such a bad thing, because it ended up as one of the most popular glass maps on the servers. But it put me off making maps for a while, that's why I never really finished it off, although I do intend to complete the final version soon :D.
Pro/Con table:
Gameplay and originality: Pro
Clean brushwork: Pro
lack of detail: Con
Repititive enviornment and texture choice: Con
I suggest adding more architextural structure to the walls. More source elements would be a nice touch too.
Instead of using func_breakable for the glass, make them func_breakable surf.
I would give this map a 2 and a half overall.
