nice map really, I looked at it and I have 2 issues that bugs me
1) The expanding, goldmine, creeps in camp mode, I really don´t like the idea, you can tower camp that safe in early stages.
Sugestion: put them normal, even if means that you can not walk there, or send the goldmine to the edge
2) I think the goldmine closed with wood, is hard to access with zeppeling, I think in this kind of goldmine there should be some space to safe land and organize the attack. Remember that the units download from the zeppeling 1 by 1.
sugestion: try to re-make that area, so a Zeppeling can have a nice safe zone, or better, make the goldmine open, actually I think those mine closed are less fun, since you will be forced to expand to the other, if both are open you can chose the expantion and the game play can be more diverse.
these are sugestion, do as you wish.
raiting 4/5
good luck and see ya
