Stone gargoyles perch on a cathedral and animate only at dusk; they petrify back to stone at dawn mid-combat. A day/night pressure curve decides when waves come. Signature: finish waves before sunrise or lose your defenders to daylight.
Gothic grey stonework, rose-window moonlight, rain streaks, gargoyle silhouettes with ember eyes.
Click, Enter or Space to start. Place and upgrade towers with the mouse and number keys, or by tapping on touch, to stop each enemy wave before it reaches your goal. The HUD tracks lives, cash and wave.
