I'm not liking how this map plays very much at all, to be honest. The first, second, and third points all seem a little... wrong. The first point, you could see at least some of all three spawn exits from one point, and two scent trees could easily have covered both exits.
The one way door that goes against the cart from the second to first point area is also a real issue. See, the second point is just too hard to push, and it all seems to be from after or just before you exit the tunnel. Seems like it's too hard to get to the cart or behind it there as BLU, but it's very easy to get behind BLU as RED. And then there's the issue of the rock, which didn't bother me at all, honestly.
The third point was hard to push, again, I think because there were too many one way or one-way-esque routes to take RED behind BLU and not enough of the inverse. That, and right around that first corner, you've got no cover pushing the cart at all- it LOOKS like it should play like the stretch of Badwater immediately before and after the first point, but I think it isn't playing that way perhaps because of how easy it is to get ABOVE the cart here on the bridge or the balconies.
Even though the heavies always seemed to come from around the corner to kill me, not from above.
Also you need at least one cactus.
