in run and gun mode, when i get a rainbow powerup, i turn off the music (shockingly) pause, go to youtube in a new tab and play the mario star theme :P
Great game, love the zelda theme XD unfortunately i have to give it a 3/5 because sometimes the notes are out of sync with the music, and i use the music for the rythym so its not as good as it could be. the third was a major improvement
Personally i want a button hunt four too. But judging by how long this one's been out, either another one isn't coming or his next one is so great it has taken this long to make
