What They Don't Sea

As a marine researcher with the Rachel Carson Research Organization, RCRO, you have been sent to collect samples of a new species of algae for an alternative energy project.

Traverse the depths of the ocean in this beautiful 2D pixel platformer, but be sure to watch your air levels! What They Don't Sea has a wonderful mix of beautiful and creepy environments, with drops of humor delivered by charming ocean creatures.

About the Development Team

What They Don't Sea was created by Team Atlantis, a group of middle school girls, at the 3-week Girls Make Games summer camp in Durham, NC. The game won the Grand Prize at GMG’s Demo Day competition in 2019, and went on to raise over $40K on Kickstarter.

Perfect girls! You just have to let people know the system requirements. For example: the OS High Sierra won't open it. So it'd be a great idea to let people know before they purchase. Have a great time! Congratulations.

Hi randyberlin! Based on the Unity version that we used, High Sierra 10.13+ should be supported. Can you please email additional info to us at info@girlsmakegames.com?

Info like what version of OS High Sierra, what error message you are seeing, and other details would be very helpful.
