Harbor Shift — Prototype Demo

Harbor Shift is a small cargo puzzle prototype. Move the harbor worker and push each crate onto a marked dock. You can push, but you cannot pull: leave yourself room to get behind a crate.

This public browser demo contains three levels. Use arrow keys or WASD, or the on-screen direction buttons. Undo takes back a successful move; Reset starts the current level again. Hint shows a suggested next direction. Completion is saved locally in your browser when browser storage is available.

The complete source-project prototype currently contains twelve fixed levels. The full source package is being prepared as a possible acquisition candidate; it is not included in this public demo, and no sale or rights transfer has been agreed.

AI assistance was used for the code, puzzle layouts, interface text and SVG/CSS visuals. The runtime uses browser features and system fonts, with no bundled third-party engine, art/audio pack or external game service.

This is an early prototype. The browser verification record covers the tested controls and viewport sizes; it does not establish physical-phone testing.
