Last Light Keep: Endless Watch is a small offline HTML5 castle-defense game. Defend three towers through five 30-second waves, pick an upgrade between waves, and defeat the Eclipse Knight. A separate Endless Watch mode keeps escalating until the towers fall. Tap or click to fire; hold and release for a wider burst.
