我怎么样更新这个游戏，而不是重新下载？How can I update this game instead of downloading it again?
如果是电脑的话，好像只能重下，把存档文件夹拉出来，然后放到新的游戏存档，手机或者平板大部分时候可以直接下载更新，不过也有偶尔需要删掉旧的重下。
You need to download it again, there's no in app update. If you are on Android, make sure you are overwriting the old app instead of uninstalling old app and installing new one.
