Okies, first of all; I don't like how the bombsite B 'window' works from the ct side. 2 jumps should be enough and there's some sort of hole between the boxes and the rock you can fall into which slows you down. And what happened to the top part anyway?
I tried it on my own computer and I dont think these two following places are supposed to be accessable:
(w00t you can also get to top of the palm tree in middle from here
)
Also I think that you can get on the rocks on middle ct side by bouncing from the rocks to the palm tree towards the corner, but couldn't quite get the jumping right -_-
Couple of crates here and there missing. There's also a plenty of misplaced textures, holes in the walls etc. etc. but I guess they aren't your no#1 concern atm. so I'll bitch about those once you have 'last version' of the map ready.
