I'm not sure what you considering tapping with the beat but the prompts are not with the rhythm at all. I've played many rhythm games and perhaps it's because they try to make it easy but the taps are not set to the place when you naturally want to tap along with the music. Consider a metronome, it provides a consistent rhythm in which you make a beat to. You can tap along with that. That's what I expect from a game like this, consistency in when one should tap not random marks along the beat.🙋
