“Twin☆Dance” is a game where players move their bodies to the rhythm of the music, having fun while also improving their health. The system converts their physical activity into points, which are displayed in the game. By incorporating elements of oshi-katsu (supporting your favorite characters or idols), players can also earn a special token called “Twinkle_coin.” These coins can be exchanged for limited-edition products, creating a positive cycle that motivates players to stay active.
