About this game

Carapace Protocol is a synthwave tower defense game where you place coral, anemone, jelly, and urchin towers on a grid to stop waves of sea creatures from reaching your reef base. Manage energy, block the enemy path with your placements, and choose mutations between waves to give your towers extra range, chain shots, poison, or area damage. Survive as long as your ten lives hold against escalating bosses.
