About the game
A small, soothing aquarium that lives in a corner of your desktop. Your pet drifts slowly through the water while bubbles and gentle water sounds accompany your work or study, with no objectives or daily tasks to chase. A timer, reminders and to-do notes are built in, and extra tanks and pet appearances are sold as DLC. Sayachi-maru Games developed and published it in 2026.

Buying is legal — keys come from the grey market, so a small deactivation risk exists. So before paying, check the seller's buyer protection.

The service where the key activates — Steam, GOG, Epic or the publisher's platform. A key for one platform won't work on another, hence the separate filter.
