this looks like you are not trying
like you are doing it for YouTube money

looks like someone needs a beta tester
(like a popular youtuber (relaxingend etc))
I have made a video to show what is wrong with the map

call it kino der

is it based on the minecraft mod? 

maybe you should turn it into a black ops 3 styled map (shaders, weapons, etc)
 

maybe you should add some black ops 3 shaders

will you add more rooms?

make this the round out
now I have your attention
make unfair mode (endless, pistol start, boss every 3 secs)

how about for dodecagon challenge it could be:
no man's land styled rounds (endless
pistol start
tranzit runners
hell hounds
panzers
brutus
pentagon thief
powerups to pause the round

is it endless?

rip nightmare
revelations beat you

you could add some cs:go weapons to make it more like dust
