Music scrolls toward the play line. Play each note right on the beat and the runner leaps from roof to roof across the city.
Trouble spots
With headphones, the microphone hears only your instrument, not the metronome or the game's sounds, so every note is easier to hear.
Listen to the first 4 clicks, then tap along with the next 12, right on each click. Use the space bar, the pad below or any key on your MIDI keyboard. This measures the delay in your speakers and keyboard so the game's timing is fair.
