Ghosts ignore all walls; only medium towers in charged seances can banish them, and candle flames push spirits into table-corner traps. Séance charge time grows with the circle size. Signature: seat five mediums at one table for a banishing storm.
Sepia and violet candlelight, velvet drapes, floating ectoplasm, round tables with chair silhouettes.
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.
