Harbor Pack is a browser puzzle prototype with 60 fixed crossings across six chapters. Rotate awkward crates, fit them around the masts, and keep the two sides of your ferry within the weight allowance. Filling the deck is only half the puzzle.

There is no timer or move limit, and undo, restart, and hints are available. The prototype is free, with payments and donations disabled. Progress stays in the browser on this device when storage is available.

AI tools were used for code, level layouts, the interface and procedural visuals, locally synthesized sound, and written copy. The game itself does not call an AI service. This is an early prototype, not a finished commercial release.

If you try it, I would particularly appreciate knowing which crossing you reached, where the controls became unclear, and whether balancing the cargo felt satisfying or frustrating. No rating, purchase, or personal details are requested.
