- Relaxing Idle Clicker Gameplay

A marimo lives in your aquarium.
Tap it to collect oxygen bubbles, and it will continue producing oxygen automatically even when you're not playing.
Use the oxygen you earn to upgrade your aquarium, improve growth speed, and create the perfect environment for your marimo.
This is a relaxing clicker game where your marimo grows little by little—even offline!

Water quality gradually decreases over time.
If it reaches 0, your marimo will stop growing, so use Conditioner to restore water quality.
Don't worry—your marimo won't die, even if the water gets dirty!
