Lighting is too bright,

Your maps clip brushes, (invis walls are inconsistent.), You use the wrong ones too in some spots.
radar image is really inaccurate, you should not use the roofs of the map.
And some parts of the map are not in it.

If you have 2 Players Or even 3 Players on the right side of T spawn you are able to leave
the map by jump crouching and boosting each other.
(with 2 you can get high, with 3 you can leave the area.)

Same thing in the first middle of the map, by the big (Conveyor) text, if you have 2 or 3
players you can leave the map. (with 2 you can get high, with 3 you can leave the area.)

2nd alley way, where the text Chuti and TE 04 is,
there is a slant wall you can jump on and again, but this time with just 2 players
you can leave the area, There is also a spot on site that will allow
you to jump up there alone.

T spawn you can get out of the playing area, by using 2 players, but also 3 to get on the roof.

On the back of B site, you can leave the map with 2 players. Same with the side.

No (Nodraw) Textures, Helps you map file size and optimisation. Use it for textures you
cannot see.

The prop window you are using, is being used incorrectly.
You must place it inside of the wall slightly, so you would have to carve out a spot for it.
