There seems to be a bug for me at the end of mission 48. Upon completion of the mission, I get the experience and cash reward screen, but after the cash reward is transferred the game stays on that screen and doesn't move on.
Like the others, I was annoyed at first that the links were broken whenever a hex ran out of units. I managed to work around it by having long chains, after which the game got considerably more fun. One thing I'd like to see changed though; when you're sending units to a neutral hex or your own hex, and that hex gets captured by the enemy, you stop sending units to that hex. It would be nice if that link was not automatically stopped as it makes it considerably more difficult to manage fighting over a particular hex.
If all your family members die (none left on the map), the game just keeps going on. Also, rearing cows generates so much income that doing anything else doesn't really make sense if you want to maximize your income.
Pressing "down" to kill a fallen enemy feels more intuitive to me than "up", but I can see how that might make it a bit too easy (time taken for instant kill is too fast). Would it be possible to ensure that it doesn't miss, at least? For me, the biggest annoyance would be when Achilles turns away from the soldier I've just knocked down, so that even though I jump in the right direction and hold "up" he fails to make the killing blow.
I really enjoyed this, but my one gripe is the mechanic for killing enemies you've already knocked onto the ground. Perhaps there could be a smoother way of stabbing them when they're down rather than pressing "w"?
