Lookin' good!

Once again, thank you very much for the criticism.

I've made room for the purple block, I've added 2 platforms in a similar fashion to the ones I just added in the White UFF version, and I replaced the shadow runes with regular grenades.

I only added 2 platforms this time because those chests actually stay attached to the wall and can be used as emergency platforms, and I replaced shadow runes with grenades to make sure people have a better view of the stage.

Items from Purple Boxes: Doesn't they glitch into the wall?
Vanilla items probably not, but mod items aren't that lucky.

My friend made several maps with PBoxes near rooftop, and items were often glitching.
Also you know the second door blocking Red Boxes (cool idea :-D ) can be glitched with ragdoll, due to space above.

Among all of this, it's difficult map, not many ground is left for duck to move.
Reminds me of Minecraft custom map seriers, Super Hostile.
It's main feature, was how difficult movement there was.
