Run n' Gun isn't that hard people. You just need to catch on to the rythm of the song. Place your index and ring fingers on the left and right keys, tap each alternatively. Just don't get ahead of yourself, you do that and the whole song gets messed up.
I'll say it again: For those who are getting lag. Turn the quality to the lowest (there's a little "Q" next to the "Ready" button, click it twice). Also, if you are running a messenger (Especialy Skype or Xfire) TURN IT OFF! As well as any other programs in use. This will reduce lag sygnificantly.
Not exactly, Babaloo, you're correct about the fact that it isn't about note imputs. There is a specific range for bronze, silver, and gold, but the only possible way to get a score of perfect, is to hit every note in the song... So you cannot get a perfect without hitting every note. Unless of course you hacked the game and made it so that you had a X5 multiplier all the time... But that would mean you have no life ^^
