About Jellyfish World
Relax with healing a whale and BGM!
Your mission is to name and raise Jellyfish.
There are only two rules
・ Feed once every 3 days
・ Clean the water diligently when in contact with Jellyfish.
It is a loose fluffy game that you can proceed at your own pace even if you are busy.
The longer you spend in contact with the Jellyfish, the faster the Jellyfish will grow.
Also, please note that the Jellyfish will die if left unattended.
Grow your favorite Jellyfish!
