On a whim, I downloaded this map to check it out. From what I can tell... it really hasn't changed from the screenshot posted.
I'm sorry to have to tell you this, but RaZgRiZ's review was spot-on.
Box Map- Check
Flat Ground- Check
Huge Wall- Check; it's even more flat and boring than the ground is.
Mapmodel Spam- Check(Though I'll give you what little sympathy I can since they are trees)
Random Lights- Check; Though a few are clearly from teleports many are completely random.
I also feel I should add:
-All ceilings are too low; Players hit them when they jump.
-There are only 8 textures used across the entire map.
-The overall geometry consists entirely of either whole cubes or 1/2 cubes; Nothing else.
-The most detailed geometry are some stairs that, ironically, do not need to be that small.
-The light over the moon gets eclipsed by the moon entirely-- Not that it matters anyway since the radius of the light doesn't reach the ground.
-All ammo and armor are placed randomly; as if someone merely dumped it all into certain spots around the map.
I'm sorry if my review seems harsh, but please note that I am merely basing my review on the usual quality of maps posted to Quadropolis.
