Nifty strategy game! Great example of asymmetric level design; each path a slightly better option for certain pieces, different patrols. Minimalism was the right choice for a game like this in my opinion, though it might benefit from coloration of the pieces (maybe shades of green or pastels to keep them distinct from the reds). On the other hand, a good general should be able to keep track of their troops without the aid of visual confirmation, so perhaps you were right in keeping the pieces identical. Guess I'm on the fence on that.
