Okay. Downloaded it tested. Just one thing appears to my mind?
What the hell you are thinking when releasing this map?
First: You dont have any point in this map just monsters couple and closets.
Second: Very small map not much exploring at all.
Third: Some rooms are almost empty only few objects here.
Final what is wrong there is not much entitys and that entertainment expirement.
Okay I know if this is your first map ever. I can understand why there are so many flaws and something else doesn't make any sense.
I know I sound like annoying asshole but this is the true.
So my hints are: Start again whole project and focus one room at the time and give it time to make that begin room like nice looking windows, lots entitys and enjoyable. Slowly make more rooms like same sizes or bigger but that way it makes sense. Not one big room with nothing on it.
