The more you play, the more you’ll amass!
Collect and care for a cluster of sentient moss balls called Momos!
With 30 unique pets available for the demo, and 500 + prepared for the full release , you can discover Momos with special designs, sounds, and rare behaviors! Then select up to three of your favorites to interact with in your bowl. Marimomo's demo includes 50 decorations to unlock!
Play Marimomo how you want: A cozy aquarium sim, or a completionist’s collectathon!
Check-in on your pets whenever you want.
Momos need no commitment! Care for your buoyant buddies anytime that's convenient for you, without worrying about common virtual pet penalties ( no pet death! )
Caring for them will increase your Momo’s friendship with you, and in return you’ll be rewarded with Bubble Chips. Use them to enhance your habitat, buy toys and décor, or cash in your chips at the Momochine and amass even MORE Momos! And be sure to check what you find in your collection. Some Momos might be extra special!
Switch to an interactive desktop overlay!
In Desktop Pet Mode you can take your momos anywhere! Watch them while you work, have them overlay your livestreams , or set them over any virtual space you want their companionship!
This mode can allow you to easily move the game overlay wherever you want, hide the game's UI, and set it above or behind other open windows so your momos never become a distraction.
Gameplay that’s reward-focused and comfort-centered.
Marimomo’s game-feel is made to be a calming experience. Enjoy sensory play and soft ambience . The atmosphere you can create has been especially designed with sleep in mind (soft ambient tank noises, a dimming feature, and ASMR, all on your bedside!)
Accessibility features include: A motion-sensitive mode that reduces fast movement and removes sudden changes on the screen, visual feedback designed to play alongside audio queues , large text and readable fonts built-in , font colors chosen for all color-blindness built-in , 3 custom cursor sizes for visibility comfort, and an easy to access dark mode for light sensitivity and sleep.
Custom settings include controls for master sound volume, music volume, game SFX volume, and Momo SFX volume.
Log in at your pace, design your habitat, and care for your faithful floaty friends. Your momos will be ready for you whenever you are!
