Delay Rhythm Echo

After a disaster called "Echo", time was brought to a standstill-people stayed where they were, and all sounds were late. You're on this side of the screen and you hear the girl's voice. She can't see you, but she knows you're there. This time, she seems to need your help. When the note reaches the decision point, press the button to adjust the note to the correct position. If too many mistakes will fail. Solve the echoes along the way with the nameless girl and reach the final ending (there are two?).
