I'm keeping this post short because I'm short on time, and it seems like you've been given some great feedback so far.

Graphics:Very, very nice. For a game genre that doesn't depend much on graphics, this one really has outdone itself..excpet for the times new roman font
Sound: Perfect.
Gameplay: I dont really play many turn based games on the computer, but I did like this game a lot. It's very tactical + strategical, and from my first glimpse of the game, it seems quite hard to master. Atm, with even just 4 unit types, the game is intense. When this game turns multiplayer, I'm sure there are going to be some very close and exciting matches, and also some freak players (who will live on the game).
Additions:
-Skip button. I found it very tiresome and tedious waiting for the AI to finish it's move. Also, occasionally I had finished my desired moves but had to repeatedly click 4 times on each remaining character to finish the move (not fun). This could all be fixed with the addition of one button
-Different terrain. I found it very repeitituous playing on the same field. If the terrain were more random (randomly loaded), players would be forced to change tactics and improvise.
Controls:I think at times that it gets quite fiddly, but overall, the controls were well structured and fairly easy to learn.

I'm sure ithe game's gonna be a huge hit when it goes multiplayer (it would even be a good singleplayer game), and best of luck.
