Harbor Chaos

Harbor Chaos is a sliding-block puzzle set in a calm, low-poly harbor. The basin is gridlocked with ships, and your red boat is stuck. Slide the other vessels out of the way, open a lane, and guide the red ship to the open sea.

Every ship moves only along its own axis — boats facing across the water slide left and right, boats facing along it slide up and down. Nothing rotates, nothing falls, nothing is placed. It is pure, calm spatial logic: read the jam, find the order of moves, and untangle it.
