There's an issue with downloads currently showing a 404 error. Looking in to it to get it corrected as soon as possible. Externally hosted files are not affected. Newly uploaded files are not affected.
Played it during a test of several maps on the TF2 EU server. Of the half dozen I tried then it had the best flow, layout and potential. Every area had possible flanks while distinctively detailed areas allowed easy learning of the map.
Some minor balancing still needs to be done on B and the elevator on B screams for a second stage continuing down the elevator (I've done that on my maps) but it's fine without one. Still it's pretty good and I hope you finish it :) .
