I played it! The map was fun :-)
There is 1 minor thing I didn't like.
@Nedro make the 1 line thick of dirt around the goldmine to 2 lines thick.
It confuses people when the try to build the hall.
I would also put a darker grass close where the treed mine is, to ease the exploration.
Something to indicate where you are supposed to chop for it :-P
I believe that all strategies are viable to this map. Walking the distance reduces the rush potential by the way.
Cheers
