Planet towers ride brass arms that orbit an orrery; when planets align, their beams fuse into a devastating syzygy strike. Gravity tethers drag enemies inward. Signature: wait for the alignment window and stack three planets on one node.
Deep-space blue velvet, engraved gold filigree rings, glowing planet orbs, ticking escapement overlays.
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.
