i found 2 ways out of map, 1 way over the walls and roofs (HUGE sc) 1 or 2 big sc's and 3-4 small

i made demos, xfire me to send you
also found some small bugs:
1 door teleports you at the place where u stand, not on the other side
some texture bugs - decals, overlapping textures
you didn't build the map from caulk --> less fps
you didn't portal the map --> less fps
the map is very big --> less fps
i dont think many ppl will be able to get 250 fps which is required to play :S
it's very confusing where to use each key, the help text confused me even more

(where's the fuckin castle, oh, lol, the East guard's tower is actually located in the west part etc)

it'll be a good idea to write the name of each place over the door and make keys different colours to be more clear... it took me 3 hours to finish the map, most of the time walking around with noclip and searching for doors
i wasn't on loading screen

naah, im jokin , i dont want it but u just had said u'll add me there
you used custom textures by rezil and pnin, got my idea for making water and my close_eyes script

also "Whoa you found Creep's office" sounds familliar
now what i liked:
nice design at some places - the key chests, the gate of hell, and some others
you removed the torches xD
the overall design is very nice
the w.o.w. ambient sound fits well the map
nice ideas: the 90 degree turn bounce, the end cap bounce, the rpg thing with keys
the map is definetely worth playing but maybe you should make a fixed version
(why didnt you give it to us to test it before releasing it to public??

)
