Defend the last light in an enchanted forest. Elowen's missing neighbours are trapped inside corrupted creatures; break the blight and watch their refuge grow around the living Groveheart. Place eight unique guardian types freely across the battlefield, combine their attacks, upgrade and reposition your wards, and choose blessings that shape your strategy. Face endless nights, varied enemies and a boss every fifth night. Painted woodland art, animated guardians and an atmospheric soundscape bring the vigil to life. Play with mouse and keyboard or landscape touch controls. Progress saves locally between nights on the current browser and device.
