>>48541269Input to screen latency is very important for rhythm games, make sure its close to 0 or you'll have to do mental math to match up with the timing. Doubly so because you can use the sound of the button presses/ hit sounds to make sure you're matching the rhythm of the song.
Other than that its just practice, once you're good at one rhythm game, you're pretty much good at them all, minus the time spent getting used to new control schemes
