This is a list of my comments I thought of as I walked around the map, in the order I thought them.
1. The OS X files in the .zip aren't needed, you can keep those out of it
2. The readme says "Do not modify", I think you should know that content to be included in the game (if that's what youre aiming for) has to be CC-BY-SA or similar.
3. The blended kurt/ textures on the ground arent working for me.
4. The rocket is REALLY easy to get to, right after spawning. I think you could move it to a more difficult / hidden place.
5. The clipping above the tanks could be greatly reduce (So the player can run across the top of them! Woo!)
Screenshots:
- The grass here might as well be the metal texture too.
