About this game

Idleness × Sound = Doting Love?!

A world irresistibly endearing, discovered beyond mere relaxation.

"Grows through idleness," "Healing through sound," "Cute characters"—Onomatopia is a gentle idle game that quietly accompanies your busy daily life.

■ Create your own "healing BGM" with approximately 350 million combinations (*)
Even when the app is closed, the world slowly grows. The sound of waves, the sound of wind, the sounds played by the Matopes... Why not freely combine them to create your own personalized ambient sound to brighten your study time or sleepless nights?

(*) This number includes in-app purchases.

■ Encounter with the mysterious creatures "Matope"
"Matope" are adorable creatures that play music. Unlock new homes and enjoy a journey to find the yet-to-be-seen "lost Matope" together with the robot Siesta. The more you collect, the more vibrant, colorful, and musical the world becomes.

■ "Matome Love Mode," a feature born from user feedback
As you are soothed by the "sounds" and nurture the world through "neglect," before you know it, they become irreplaceable... A new feature, "Matome Love Mode," has arrived to answer that feeling. Stroking, poking, or hugging your favorite Matome will make them happy. The "affection level" that deepens through interaction may bring out special personalities you've never seen before.

■ "Siesta," the researcher of your homes
"Siesta" researches homes and Matome. Sometimes she'll inform you of a "lost Matome" that has wandered into your home, or give you hints on how to nurture your home. At the end of the research journey with Siesta, a form of Onomatopoeia that no one has yet seen may await you.
