When a run ends — your headquarters falls, you clear the final wave, or you choose Restart Run — Gold you bought and didn't spend carries over to your next run (the end-of-run screen shows how much). Gold earned in play belongs to that run and is used up when it ends. Ordnance Points and Armory upgrades are permanent and carry over to every run.
Close and reopen the game — a purchase that was interrupted is delivered the next time the game starts. If it still hasn't arrived, email us with the order number and we'll sort it out.
Yes, from version 1.0.1. Your lasting progress (Armory upgrades, Ordnance Points, achievements, Endless records) is backed up to your own iCloud (iPhone, iPad) or Google Play Games (Android — sign in to Play Games). On the new phone, install the game and sign in to the same Apple ID or Google account: the backup is put back automatically, or use Settings → Cloud Save → Restore from Cloud. A run in progress stays on the old phone. A Commander Pack you bought comes back with Restore Purchases on its page.
Purchases are processed by Apple or Google, so refunds go through them: Apple · Google Play.
Open Settings and lower the Graphics option. Low turns off shadows, which makes the biggest difference on older phones.
遇到问题请发邮件到 worldtab.app@gmail.com， 购买相关的问题请附上商店收据里的订单号。
一局结束（大本营被攻破、打完最后一波、或选择"重新开始本局"）时，购买的金币里没花完的部分会保留到下一局（结算界面会显示保留了多少）；打怪赚的金币属于这一局，局结束时清零。军工点数和兵工厂升级是永久的，所有对局都保留。
先完全关掉游戏再重新打开——中途被打断的购买会在下次启动时补发。还没有的话，发邮件附上订单号，我们来处理。
可以（1.0.1 起）。长期进度（兵工厂升级、军工点数、成就、无尽纪录）会备份到你自己的 iCloud（iPhone、iPad）或 Google Play 游戏（安卓，需登录 Play 游戏）。在新手机上安装游戏、登录同一个 Apple ID 或 Google 账号，备份会自动恢复，也可以在 设置 → 云存档 → 从云端恢复。进行中的那一局留在旧手机上。买过的指挥官礼包在礼包页点"恢复购买"即可找回。
