This is great, Yellow. I loved what I saw in the forgethrough I did this morning. I'm glad you decided to overhaul this thing and it obviously plays the better for it.
I doubt you'll do another update, but one cool thing I thought of when I was traversing the tunnels was to open this fence wall up for asymmetric games

and simultaneously close off the tunnel next to it. It would allow for another easier, but potentially deadlier way back with the flag. Could be something you could incorporate into your next map, since it's really nothing that warrants an update. I'm a sucker for maps that change up a little depending on the game. Congratulations on the feature, sir.
