Hay! I like this one!
I dig the light rays, I like the floating platform, and I like the terrain visible all out there and stuff.
This one I think plays much better in the non-melee Duel options, and That's OK! Hehe, IMO we need maps that work in those other options as well. And it can still work in melee.
Nice map.
I would suggest a few things, though, and I would like to replay it more as well. So far I've only played it in higheest detail settings, with a lower level bot..
Anyway, I personally don't prefer invisible walls to end the map. Some folks are fine with this, and it wouldn't be the 1st map to have them. But I much prefer some sort of 'visible', or 'natural' boundary. For example, making this a rather large hilltop, with edges to fall off. Being as large a playing area as it is, I don't see that as a problem. There is plenty of room, so if you got knocked off the edge, that'd be your own fault.
I agree I guess that the proxies don't seem to fit the theme. But they don't look horrible either. I think they cold stay, but better ideas also might be out there.
IMO, the ChaosArch floating out in the sky also seemed a bit out of place. Again, it looks Ok, but it might also be neat with just teh clear blue sky out there.
I have never preferred teleports that have no visual clue. In the top platform center, the teleporter, at least on my ancient machine, had nothing visual. Not a big deal.., but still.
As far as the center of the floor, well, I dunno. Not sure what might help to breat it up, or if it's absolutely needed, but it's not a bad idea. Obvsiously crates aren't the answer ...

...but maybe something. Perhaps it's sunken just a bit, instead of raised somehow. I dunno..,
But I like this map. Will play it again, making sure I have latest version, and comment more. It's even got great shots in the preview map menu there, and a nice readme...
Nice work LeFilou!
