Good map. Great Idea. No glitches. I played against computers, and ti worked fine. I want to try it on the internet.
Good balance, equall sides. But although I only played against the computer, I wouldn't say that it could be hard, because you give alot of space to build more walls. I'm sure with the amount of stone you can extract, and the space you can build, you could maybe build 3 double layered walls, will granualed walls, and maybe some moats there. So it would be quite easy to defend yourself. I would put it to medium, or easy, because you have lot of grass to build your farms.
Its a good idea, and I like the walls that you put to denfend each team. I like the architecture.
Map Design: 4
It seems that you worked on the plains abit, adding some sand dunes, but I believe you could work on it abit more, to maybe put it to a 5
No real story, but better than putting it empty. You put isntructions for it to work its best, with all humans opponents.
Its a nice map. First impression I had was that I really didnt like how you mixed the lanscape with already-placed walls, which really made it look unnatural ( from the mini-photo). But I understood the reason of those walls, and I enjoyed the game very much. Lots of fun!
