Hi Sanuich, responding to both your comments.
1) The order system is pretty flexible and does give a lot of control, especially if you use the option shift and 1-9 keys - but the battle is supposed to be somewhat chaotic and hands-off to some extent.
2) Unit abilities are explained in the tooltips when you mouse over them. Another good way to experiment and get to know them is through the Duels gamemode, where everything is a bit more controlled.
3) AI is currently being improved, and in the next update it will be slightly more sophisticated.
4) There isn't really a list since it's currently a one-man venture. But I can tell you that for the next couple of weeks until v1 release, it's just polish polish polish, building out features already in the game, explaining things better, etc. For v1, there'll be a new faction (already implemented but in balance testing before being released)
