Sing, O Cat!
Read full descriptionHide full description
Challenge your memory of melodies with Mayah, the magical cat. ■ When you tap the flower keys of Okinawa, Mayah the cat begins to sing. If Mayah can sing the same melody as the forest spirit, the forest will bloom with flowers. At first the melodies are short and simple, but the more you play, the longer and more challenging they become. Fill the forest with blossoms! ■ Variety of Sounds As you progress, you can unlock different instruments—Sanshin, Koto, Guitar, Flute, Marimba, and more. ■ Encounters with Okinawan Butterflies Tap the butterflies that appear randomly to replay the spirit's songs. Twelve species of butterflies will visit the forest. Collect them all! ■ The Ruddy Kingfisher Sometimes a red bird flies across the screen—the Ruddy Kingfisher. If you’re lucky enough to tap it, it will rescue you when you face game over. ■ About Maya Mayah was once a weak little kitten, rescued in the forests of Okinawa by Mr. Higa. In the Okinawan language, "mayah" simply means "cat," so it’s a little unusual as a cat’s name. But Mr. Higa’s wife, who is from Tokyo, loved the gentle sound of the word and gave it to the kitten without hesitation. Mayah’s ears and fur patterns are a little different from most cats. It loves nothing more than to wander through the forest, listening to the wind and the rustle of leaves, setting off on her own adventures. Mysteriously, whenever Mr. Higa goes to fetch Mayah, he finds the forest in full bloom with flowers that shouldn’t even be in season. Mr. Higa can’t help but think: "Mayah must have a special power." ■ Note This app is a work of fantasy. It does not encourage releasing real cats into the forests of Okinawa. ■ Credits / Special Thanks VOICEVOX:Miko Ouka(CV:Mizuki Akano) イラスト沖縄: https://illust.okinawa/ 効果音ラボ: https://soundeffect-lab.info/ VSQ plus+: https://vsq.co.jp/plus/ 魔王魂: https://maou.audio/
