About Shrouded Harbor Signals
Shrouded Harbor Signals is an offline puzzle game built with SpriteKit. You play as a lighthouse keeper on the Atlantic coast, guiding ships through fog, rain, and storms by choosing the correct signal response for each vessel's intent.
Journey across five historic lighthouse stations — Portland Head, Boston Harbor, Cape Cod, Sandy Hook, and Cape Ray — spanning 50 night shifts from the 1930s to the 1960s. Each station introduces new equipment and harsher weather.
Every shift challenges you to read incoming ships, judge their intent (inbound, outbound, anchorage, distress, or unknown), and reply with the right signal before patience runs out. Manage your mistakes and guide all required ships to complete the shift.
