I'm not really going to comment on the gameplay because what would be the point. but as a suggestion you could really have made the architecture and custom objects more interactive by way of a practical improvement. you've clipped off a really cool terrain vehicle that you could hide behind, or place an item on, and make the boxes smaller and the girders accessible. Little perching spots like that make all the difference in simple design fun-size maps.

When I see RL with 2 packs of rockets near the LG with 2 packs of LG-ammo and two 25 hp bubbles, I wanna cry immediately. :C
