I have a simple English version now. Please check the link below.

In ancient battle field, people used pigeons to transfer messages.
You are the soldier to send the pigeon to the city.
Drag a command card from right side and click a city to send pigeon.
You don't have to follow the order, but might be lost the trust from general.

Translation:
* Upper right number: trust number
* Right command cards: 1st line: from what city, 2nd line send how many troops, 3rd line to what city.
* Cities status(from left to right, up to down): city name, status(at war or not), our troops, enemy troops, citizen.
* Upper left: Our total troops, enemy total troops.
* Lower left box: the messages from cities.

Known bugs:

1. Sometimes when all cities not at war, it will not go to ending.

操作：扮演傳令兵，拖曳右邊的命令給鴿子送信，如果不遵守命令，可能會被扣掉信任值

已知bug: 有時候不會結束...希望我有時間修...
