Buy Under the Blue Horizon PC key

Under the Blue Horizon is an idle simulation game with an aquarium you can place anywhere on your screen, alongside your work, games or other activities. You raise fish and expand your sea while the game runs as you do other tasks on your computer.

Raise fish and expand

Fish grow by eating shrimp, and you can raise and observe many different species. Fish drop byproducts that you can turn into Aqua, the currency used to expand the sea and build and place structures.

Friends and features

Crawfish and jellyfish can help you acquire resources more efficiently through their placement. Special friends provide functions such as optimization and music, as well as new buildings.

The interface includes zooming, monitor switching, window repositioning and an always-on-top display.
