Niko, I'm sorry if it appears that I have something against you. I don't, but stop trying to make everyone use Polyworks. Not everyone likes it's style.
Umm...come on, this map is
too simple. Make something worth your time. At least make 6 decently shaped platforms with some nice scenery on each. Maybe some mossy rock platforms? Whatever suits your style.
You can immediately tell that hardly any effort was made into making something like this, and how much effort you put into a map really counts when it comes to releasing it, especially when you release a map you yourself like and would want to play.
Maybe you oughta work on something small but nice n' fun like a mini arena map
