"Inspired by roguelikes, adventure games, and elements of the survival genre, Aquamarine tells the story of a lone space traveller who is marooned on an unknown planet covered in water. Players must navigate their humble escape pod through the alien ocean depths, discovering its secrets, recovering their crashed ship, and hopefully escaping with their life.

Aquamarine is a turn-based game, emphasizing defense and tactical maneuvers over combat, and focuses on collecting and managing limited resources, deciphering a dynamic ecosystem, and unraveling the planet's mysterious history through puzzles and exploration. Over the course of the game, players will upgrade and customize their escape pod with a number of special abilities and tap into the planet's natural elements to power their progress."
