進度會不見嗎？ 進度會自動存在你的手機裡。1.1 版起，只要手機登入 Game Center 並開啟 iCloud 雲碟，進度也會自動備份；刪除重裝或換手機後，用同一個帳號打開遊戲就能找回。
需要連網嗎？ 不需要，沒有網路也能玩。Game Center 備份、看廣告領獎勵和更新提醒才會用到網路；商會排行榜上是遊戲裡的電腦商人。
需要花錢嗎？ 不需要，遊戲沒有內購。1.2 版起可以自己選擇看廣告領獎勵（例如體力、議價券），廣告不會自動跳出來，不看也能正常玩。
For questions, feedback or bug reports, email lastpiecestudioservice@gmail.com. Please include your device model and iOS version.
Can I lose my progress? Progress is saved automatically on your device. From version 1.1, if your phone is signed in to Game Center with iCloud Drive on, it is also backed up automatically; after reinstalling or on a new phone, open the game with the same account to get it back.
Does it need the internet? No, it plays fine offline. Only the Game Center backup, optional reward ads and the update reminder use the network; the guild ranking is made of in-game computer merchants.
Does it cost anything? No, there are no in-app purchases. From version 1.2 you can choose to watch an ad for a reward (such as stamina or haggle passes); ads never pop up on their own and the game is fully playable without them.
