Very enjoyable game!  Feedback:

1. Orders should remain between battles, including autobattle.  If I set up a complicated plan, I don't want to have to redo it every new battle.
2. Lancers shouldn't attack like knights, but like lancers; riding through enemy forces to the other side, then turning around once they have gotten far enough that they will be able to accelerate to full speed and do it again.  They should also target the strongest enemy forces, largely ignoring forces that have less than half of the strongest.  (I've yet to come across a game that uses lancers realistically.  Will you be the first?)

Cheers!
