This map does feel very nice and open, which fits the theme of the map, however edges to wall displacements are obvious, and there seems to be inconsistent clipping regarding the rooves of the map.
Personally I believe that this map is really wellmade. it encourages teamplay in order to win and it's unique which is really cool. I had a lot of fun playing the map even if we lost 90% of the times.
anyway good luck with the map
