The volcano demands tribute: you feed towers into ritual circles as sacrifices to redirect eruptions onto paths; unappeased, the mountain itself destroys your grid. Signature: sacrifice your best tower at the summit to trigger a targeted pyroclastic flow.
Obsidian black, ember gold, tribal glyph circles, falling ash, sacrificial fire glow.
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.
