Macro world inside one tide pool: snail turrets, crab pincers and anemone snare zones sit on rock islands; every surging wave resets water levels and drowns or exposes positions. Signature: bait the wave into a surge, then harvest stranded enemies.
Turquoise macro water through glass, wet rock textures, anemone neon, sun sparkle caustics.
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.
