🌊 A glass dome is the final barrier between an underwater kingdom and the dangers of the abyss. Repel sharks, orcas, giant squid, and ancient sea monsters. Build harpoons, electric coils, sonar weapons, and other defenses, then upgrade and position them wisely. 🫧 Every victory earns pearls for repairs, stronger weapons, and new structures inside the dome. The deeper the kingdom descends, the tougher the enemies and the richer the rewards become. Complete missions, unlock permanent improvements, and time a powerful sonar wave to stop crowded attacks. Can you keep the dome intact where sunlight can no longer reach? 🐙
How to play
Tap enemies to throw a harpoon. Select empty mounts around the dome to build weapons, or occupied mounts to upgrade and replace them. Trigger sonar against groups, repair damaged glass, and expand the kingdom. 🫧
