The game is set in a vast alien ocean where the player character explores and learns more about the world.

In Aquamarine, players take control of a space explorer who has crash landed on a small island on an alien planet.

Using resources found from dives the player can upgrade their pod or invest in the island.

If the bar reaches zero, the pod breaks and sends the player back to the island.
