First: I agree with Sailor, take out the impassible. He's right, what it blocks wasn't bordering in the first place. If you really feel it's confusing, put "Aisles only passable where bridged" or some such somewhere on the map.
Second: I'm with Wong: the little stick people seem.... tacky? no that's an exaggeration... extraneous to me. They don't really add to the graphics, and they have nothing to do with the game play. I like the shopping cart idea, have a couple sitting around, but the store is viewed top down, so having side view people really seems like you're stretching some point. (though I'm not sure what he means by his comment about moderator subjectivity...)
third: interesting:

I think maybe some players will target the outside and some the inside..... Personally, i think there is a little too much difference in reinforcements for the difference in defensibility, but meh they're pretty close either way. I'd probably start in one corner and try to take an edge or two and then a center, but that's just me (and maybe the reason I'm a cook now, too...

)...
fourth: I just want to put a plug in for purely classic game play, you don't need an objective (can you tell what kinds of maps I like to play

)
fifth: Why haven't I commented before now?? I remember seeing this in the ideas sub-forum and thinking, hey, that could be neat... looks like you're making progress, don't give up on it!
