I'd give the map a +1.
I just had the time to check your map out. I think it's fine, when you touch ww2 and the hitler references in this map, you need to be careful to not be disrespectful towards the victims of that time, especially if we want to upload it to the server, but this map aims to make fun and mock that ideology. I checked it out from the blue team/attackers side. And I didn't see any obvious fails. When you finish the map and you have to run back out due to some shocking revelation (that i don't want to spoil) how much time did you plan for that? There is no timer and it feels like there is really just like 60 seconds to run that map backwards (keeping in mind there might also be still some unactivated traps). But i liked the thrill. I have not seen swastikas, just the hitler ragdolls that seemed pretty harmless. You have a german quote in it, in the tunnel for the trap where hitler sits on a desk. Something about the german luftwaffe, it was harmless aswell.
I tried to play it from the red side and while the traps worked, I didnt find out how to move from one area to the next, is red supposed to be teleported when blue reaches an exit?
In the 3rd area, somewhere in the middle, there were some tanks, about 8-10 in a row but the red team had no trap button for them. Are they just for design, i'd guess that much as of right now.
The intro to your map takes around 30-45 seconds, i didn't really run a timer on it. Keep in mind that it might take away some of the fun, although I understand you did that for storytelling purposes.
I'd like to give it a try on the server, good luck
