Ladies and Gentlemen, we have finally taken Verticality, "To the Next Level".

 

I am not sure how this would play competitively, but I think you could make some cool minigames on it.
That being said, being someone who really focuses on aesthetics, I would suggest playing around with accents to add some detail to your maps. Also, putting some numbers for each floor to designate what floor someone is on. Perhaps putting some teleporter doors that have numbers designating which floor they will send you too may also make gameplay smoother.

that being said, it is a really cool idea, and I think you have some potential to make a fun gametype out of this
