How to play

Tap Begin on the title screen. Tap a reachable path to walk. Tap a pump to approach it and move a measure of water. The small lever on the pump reverses its direction; longer levers operate other machinery.

The water is shared between basins. Lowering one basin raises another, changing which paths and platforms can be reached. At empty or full endpoints, a pump may move water back; two empty basins cannot supply water.

Need a clearer view or a hint?

Drag empty space or use the camera buttons to change your view. Open Assist to see the current objective, named actions and A quiet hint. The pause menu explains interactions.

Can I undo or restart?

The top toolbar provides Undo and Reset this space. Undo restores an action. Reset returns the current scene to its starting state.

Where is progress saved?

Progress and the tutorial dismissal are stored on this device. When saved progress is available, the title screen offers Continue. Start a new shift starts the campaign again and replaces the active local save. Progress is not synced by the game between devices.

Deleting the app removes its local data. Reinstalling is not a troubleshooting step to try if you want to keep your save. Device backups are managed by Apple; the game has no developer account or remote save-recovery service.

No sound or the harbour does not load?

Check device volume, Silent Mode and the in-game sound control. If loading stalls, close and reopen the app. If it still fails, send us the device model, OS version and a screenshot of the loading screen. Please keep your installation if preserving progress matters.

Do I need an internet connection or an account?

No. The game assets and synthesized audio are included in the app. There are no advertisements or in-app purchases. This website and sending support email require an internet connection.

怎么玩？

在标题页点击 Begin 开始。点击可达的道路行走，点击水泵走过去并移动一单位水；水泵机身上的小拨杆可以换向，长拨杆用于操作其他机械。水池之间共用有限的水，水位变化会改变可达道路和浮台。两个空水池无法供水。

看不清或卡住了？

拖动空白处或使用视角按钮观察港口。打开 Assist 查看当前目标、具名操作和 A quiet hint 提示。暂停菜单也有操作说明。

撤销、重置和存档

顶部工具栏提供撤销和重置当前场景。进度和教程关闭状态保存在本机；有存档时，标题页可选择 Continue 继续。Start a new shift 会重新开始战役并替换当前存档。游戏不在设备之间同步进度，也没有云端找回服务。

删除 App 会移除本机数据；如需保留进度，请不要把删除重装当作排查步骤。设备备份由 Apple 管理。

没有声音或无法加载？

检查设备音量、静音模式和游戏内声音按钮。加载卡住时可关闭后重新打开 App；仍失败时，请提供设备型号、系统版本和加载页截图。为了保留存档，请先保留现有安装。

需要网络或账号吗？

不需要。游戏资源与合成声音包含在 App 内，没有广告或内购。访问本网站和发送支持邮件需要网络。
