I see you are having a hard time with this map and I honestly dont understand why. This map from the start was on a good rail and while the time went on you continued changing and working on it like any other map. We reached A20 and I wonder. Since the map was so fun to play and people liked it a lot why do all these changes keep happening? Maybe you are experiementing which is always a good thing but I am afraid this map will turn out bad in one way or another.
I hope I am on the wrong side here and I am looking forward to playing this map in the future again.
