Played beta 2 on superman's server. Two things I noticed:
1) There needs to be a faster path from the spawn to the high bridge. Whenever I tried to go that way, the round would basically be over by the time I got to the middle. Everybody just rushes to the middle, there's a big bottleneck, and a team pretty much wins or loses at that point.
2) Need more paths to the lower flag. There are lots of entrances to the base, but unless you're up high (which is too slow, see #1), it looks like the only path to the flag is a single ramp.
Edit: Upon looking at the map again, I see there are some ramps available, and the other side of the platform isn't actually blocked by the planks to the high flag. I would consider replacing the box and X with just a single ramp. That box feels really slow and awkward to jump on, and it's not an obvious path at first glance.
I've uploaded this map to the beta server as well. Let me know if you need the login.
Oh, and upload your map source somewhere to keep it safe before your computer dies. It would be a shame to lose it.
I think I suggested this in the demo, but I would strongly recommend getting rid of the water in the base. It doesn't really add much, and it's a real framerate killer for low end machines.
