First time I played it was this weekend, we won as attackers just before time ran out.
Played it again, also as attackers, but stalled out just past the two bridges.
I didn't think it was the least bit brighter than any other sunlit daytime map. I dunno, I saw the gamma-issue screenshots before I played it, but in-game it sure didn't give me the impression of being any different. Most definitely not a lot different.
I liked the design, tons of cover, cool emplacements, nice wide flanks. Most emplacements I didn't see used very well by the defenders, but I haven't played axis on it yet so I'm not sure why.
It's got wetlands, trenches, bunkers, bridges, open areas, a hill, villages, a warehouse. And tons of cover and defilade and foliage all over the place.
Maybe some small time/tickets tweaks could be called for, but I haven't enough experience on it yet to have a firm opinion in that regard.
A masterful effort, in my opinion.
