Harbor Pack

Sixty small crossings. A few awkward crates. Everything has a place.

Harbor Pack is a browser puzzle prototype about fitting cargo onto a ferry while keeping its left and right sides balanced. Rotate the crates, work around the masts, and try another arrangement whenever you like.

• 60 fixed puzzles across six chapters
• A route from simple shapes to crowded decks and careful weight choices
• No timer and no move limit
• Free undo, restart, and hints
• Chapter selection: revisit any crossing
• Local progress and unfinished layouts saved on this device when browser storage is available
• Mouse controls, on-screen buttons, and R / Z / H shortcuts
• Optional synthesized sound, off by default

How to play Choose a crate, then click or tap the deck square where its marked + tile should go. Two dots mean double weight per tile. All crates must fit, and the weight difference must stay within the crossing's allowance. Tap a packed crate to move it. Use the chapter selector to explore another part of the voyage.

Prototype and AI disclosure This is an early prototype, not a finished paid game. AI tools were used to develop the code, level layouts, interface, procedural visuals, and written copy. The layouts are fixed and were checked for solvability. The visuals are drawn in code, and optional sounds are synthesized locally. The game itself does not call an AI service.

There are no in-game accounts, ads, payments, or analytics. Saves stay in this browser; they do not sync between devices and can be lost if site data is cleared. itch.io has its own account, comment, and site data practices.

Feedback is welcome Which crossing did you reach? Where did the controls become unclear? Did balancing the ferry make the puzzle more satisfying, or just more fiddly?
