I feel in a mood of another complicated rating, because I can and it's free.
I don't like the order you gave us, to not use BW for our maps. What is BW stands for Base Wars in some maps? I would alter the tag.
But, back to the rating.
First screen... Looks like a nice start to an ordinary Deathrun map. I found it kinda basic, I would add some effects, for giving the map some eye-candy features.
Second screen is pure horrible, Because it lacks quality sprites, and there's alot of them to use for that kind of trap, so it's still pretty basic and looks bad.
Third Screen looks a little better than the first and second one, and it looks like a rush (only more than 1 players can make it through.)
Fourth screen, is kinda werid because of the weapons, you don't need this much weapons, if they respawn. And the design still looks basic.
Fifth screen looks like another rush, so, originality is lacking here.
But the map is overall big, and playable.
I would make it nicer, and do some more traps, using better sprites, and stuff. Good luck in the next maps. :3
