This is a classic strategy tower defense game centered around "Protecting Seagrass." Players must deploy various seagrass and jellyfish in the ocean to defend against invading sharks.

Jellyfish, by absorbing these nutrients, can unlock bubble attacks. Through a series of defensive actions—production, defense, and shooting—players must adapt tactics flexibly to achieve the goal of protecting the seagrass. Come and give it a try now.
