遊戲有問題、建議或想回報錯誤，請來信：lastpiecestudioservice@gmail.com。請附上手機型號和 iOS 版本。
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，這是單機遊戲（只有 Game Center 備份會用到網路）；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，也沒有廣告。
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 is a single-player offline game (only the Game Center backup uses the network); the guild ranking is made of in-game computer merchants.
Does it cost anything? No. There are no in-app purchases and no ads.
