# Tethyscope

> Have you ever wanted to explore the depths of the ocean? In this submarine simulator, realistic ocean floor bathymetry is home to a range of flora and fauna. Take photographs and sell them to upgrade your submarine - the more species in your photos, the more they are worth! Observe and record different varieties of animals in your catalogue - an albino blue whale, a giant Japanese spidercrab, and many more... PLEASE NOTE: I have not yet uploaded a version of TethyScope that works for older machines that do not support Vulkan (modern graphics API). I believe computers newer than 2013 should have support for Vulkan. If you purchase TethyScope and are unable to play it due to this issue, please contact me for a full refund.
