"Super Marimo Depth" is a deep sea adventure game where players help raise marimo as it sinks into the sea - showering it with affection to help it grow and avoiding obstacles as it delves deeper and deeper.
When game-play starts, marimo plops into the sea and starts sinking.

As you go along, take in the mozuku (a kind of seaweed) that floats about under the sea to help marimo grow.
Marimos main source of nutrition is mozuku, so have the marimo eat a lot of it.
