I kind of intended them to have some "drive by" attack strategies that you wouldn't get if they moved after your turn instead of after the enemy turn. Not really sure how to make those pieces more clear
After trying it a few more times, I finally grasped the concept of momentum pieces(and why it checks for 'future' places). But there's just too much to think about in this place. I'm never going back to this kingdom again :P
By the way, the game freezes with high probability as it progresses into the latter stages.
