From what I observed, the difficulty level only affects when the trail of the clubs change (which happens at combinations of 10, 20, 30, 40 and 50 correct actions) and when the more intense background music is played (that happens at a combination of 30 correct actions), but does not seem to influence the routine as a whole. The replay is played two times in order to see the complete replay the second time.
