Well done on taking a simple premise and managing to turn it into a fun experience with friends.
It was quite stressful when your army began to run low and your opponent was near your valuable gold supply. That made for a fun environment to take part in.
I don't know if you had this intention in mind for players, but one thing I found to be helpful, was to fold a bit of the bottom of each army-man to allow them to stand up straight. This made maneuvering them a lot easier.
Good game, and well done on delivering an enjoyable piece of content. :)
