It was pretty good playable, even though I had to play it a few times in a row to get it. But I wanted to get it, it was pretty interesting.
Balance, hmm, well it was rather short. And you could really see that it was a scenario out of a campaign. So, I don't think balance can be judged here.
Pretty creative points there, these black riders running past and being killed in one hit. I checked it in the editor and I think the graves were pretty cool.
Map Design: 2
Not really good map design here, too much plain grass A, try mixing some terrain and put down some grass. Though, you did have some variety in elevation and that looks really good. So I think some more sand and other types of grass would do the trick.
It was a bit lacking of instructions. You could at least have putten in a readme telling people where to put the .ltg(or was it .lgt) file. I just happened to know that, because I know a lot of aom so I knew where to put it in. As for the story, there could be a small intro or something, and a message saying check the onjectives.
It might be not one of the best, but certanly not the worse. Improve some things and put that in the final campaign, at least, I take you are making a campaign from what you said. Also, make a better description of the file we are downloaden. Make it interesting.
As for other people, but the .lgt file in Age of Mythology/date.
