, developed by Pixel After Pixel , is a business simulation game where you build and manage underwater cities. Unlike the first game, it features a more lighthearted, cartoonish art style and focuses on three distinct ways to play:

The narrative follows your journey as an underwater developer tasked with restoring various marine habitats, building massive tourist attractions, and protecting the ocean from pollution and disasters.
