Harbor Haul
Real physics, not edge timing. A harbor crane swings the cargo; tap with one thumb to drop it onto a barge, where glass cracks, barrels roll and the wind pushes. Play right in your browser. (Korean title: 부두 한 짐)
Key Features
- 10 kinds of cargo, all different: Small crates, containers, beams, sandbags, steel blocks, L-blocks, glass cases, barrels, wedges and buoys. Glass cracks on a hard landing, barrels and buoys roll and then lock, and sandbags stick.
- 5 ports, 40 contracts: Each port has 8 contracts and brings one new physical rule: wind, glass, ice and storm. Every contract has three star goals.
- One hand, portrait: Tap while the crane sweeps to drop the cargo and use the rotate button to turn it. A contract takes about 30 seconds. On a computer, use Space and R.
- Daily Contract and Free Stack: The Daily Contract gives everyone the same cargo order for the date; Free Stack is endless until it all comes down. No server and no sign-up.
- 5 upgrades, 16 looks: Spend coins on upgrades and looks for the crane, barge and crates. There are no random loot boxes, and there are 12 medals.
How to Use
- Pick a contract and start.
- Tap while the crane sweeps to drop the cargo where you want it.
- If a piece sits at a bad angle, rotate it before you drop.
- Deliver the required number standing to clear; hit the height and time goals for more stars.
How It Works
The rules and physics are code kept apart from the screen and run on a fixed-timestep physics engine. Our Js drew the crane, cargo, barge and screens in code; the 5 port backdrops, the app icon and the store key art were made with generative AI (Google Gemini), then picked and edited by our Js. AI tools were also used during development. Music: "Carefree", "Invariance" and "Clear Waters" by Kevin MacLeod (incompetech.com), licensed under CC BY 4.0, shortened and looped.
