Looks very nice so far.
I'd avoid the double fence maybe. Btw. you can jump over the fence.
What about "minclientbuild" "36/37?" and "message" "###"?
I'd also add one paint/smoke grenade with the dialogbox and
press # to throw....
Maybe you could make the dialog boxes
visible as long as they aren't read, that new people don't forget anything. A colored and flashing lighting point would be great.
It's a little bit confusing that you can grab a CTF flag, run to SIEGE area and get the cap at the wrong time. Might be hard to understand and realize for new people don't knowing the different game modes. Not sure if it's still possible after the code changes.
"Nice Air!", loool
The lights after the first jumping room sometimes block me, you might want to add clip brushes there.
Maybe add one more dialog box in front of the closed door, if someone missed the dialog box at the button.
There's also a black face at the door if it's opened.
Red: I'd rotate these faces.
Blue: I'd move this face a little bit.
Red: Why did you add those holes?
Red: I guess you did that consciously. In my opinion closing this
hole would look better.
I hope we can test the map with all functions soon. Great job.
