Analog-TV ghosts leak from a haunted broadcast tower. Antenna towers fire directional lobes; switching the channel each wave retunes which enemy types are vulnerable. Signature: find the right channel for each ghost frequency.
CRT greyscale with rolling scanlines and static snow, phosphor-green overlays, rabbit-ear 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.
