Somebody keeps switching to this map on the beta server, so I figured I'd post some feedback on it again. I'm not sure if Silly is still working on it. My main complaint right now is that it hurts my eyes to play. The area just outside the main tunnel is like all super bright yellow. It's lit with big lights, but it's day time, so that's kind of pointless. I'd take those out (or at least dim them) and use sun lighting. There are no shadows cast from the sun. The lighting in the upper areas of the tunnel is OK, but there are several misaligned light brushes there. Also, the map is mostly mirrored, but with slight differences that probably make it unbalanced (one side has a ramp on the upper platform, but the other does not, etc.).
The bottom path is more of an annoyance than anything, especially since that bridge thing has holes in it that drop all the way down. While we were playing, I witnessed a new player on our team wander around the bottom area trying to figure out how to get out as the other team captured the flag. He climbed almost all the way up the wooden pole, then fell back down and wandered around some more. Maybe it could work with a big jump pad, but ladders are far too slow and lead to the same room as the main tunnel, so there's not much of a benefit to it.
