Lighthouse Keeper

You are a lighthouse keeper on a stormy night. A cone of light rotates around your central tower — move your mouse or drag to sweep it across the dark ocean. Ships emerge from the fog at the edges, drifting toward the lighthouse. Each ship is only visible when caught in your beam. Hold a ship in the light for over 0.5 seconds to spot it (+10 points, it retreats). If a ship reaches the center unspotted, you lose a life (3 total). Tap or click for a brief flash that illuminates everything (8-second cooldown). Reach 300 points within 60 seconds to survive the night.
