About Keeper Light

Keeper Light is a survival action game built around a lighthouse. Each run alternates between daytime and night. During the day you spend your resources on upgrades for your boat and for the lighthouse beam. When night falls, waves of enemies arrive, and you have to hold them off so the lighthouse stays standing.

The nights grow harder as the run goes on, so the choices made in daylight decide how long the light survives. The split between preparing and defending gives the roguelite structure a clear rhythm, and the beam upgrades make the lighthouse an active part of the defense rather than just something to protect.

The game was entered in Vibe Jam 2026 and runs on Three.js. The creator describes it as a first game made for a game jam and says it was built with Cursor.
