I don't think you should have released it yet. The middle route is still pointless because it is very easy for the defense to contain. Put an incentive to go there, like health or nades. And low, although it has a slight slant, you can basically shoot from one side to the other as you spawn. And I don't like how you have 2 completely different spawn areas either. The roof is too thin, but that's not a big deal. Visually it looks great, but in terms of gameplay, I think you should rethink it a bit more.
