Guiding Lights is a 2D lighthouse simulation game, where players take on the role of a lighthouse keeper. By day, they prepare for the night by checking stations, like the schedule board, route map and weather station to plan for incoming ships. At night, players guide ships safely to shore using the lighthouse beam, through changing conditions and rising challenges. As ships reach safety, players earn money to upgrade their lighthouse equipment and improve the outcome of future nights. Over 31 in-game days, players carefully prepare, adapt, and aim to guide as many ships as possible.
