I don't believe I've ever commented on a game before, but this is worth it. While I'm sure it could use some minor additions, what you've done here is seriously amazing. I don't think I can praise this enough; random clicks suddenly sound absolutely incredible. If there was a sixth star, thats what this would get.
Even though it definitely has some problems, like the slowness, having your guys retreat at the same time as theirs, and a wedge attack formation that only contacts enemy shield walls at one point, it has a definite total war feel which is pretty awesome. 4/5 for a great attempt.
