The third song gets a little bit difficult (when you have to do the repeated multiple-fingered chords), so hit the 'A' and 'S' key with your left hand, and the 'D' and 'F' key with your right. It could get a bit confusing but if you keep doing it, you might be able to get a decent score. Mind you, this is on the 'Geek' difficulty.
Almost hit the notes as if your hitting them a quarter of a beat too slow. This way, you'll get perfect on each note.
Use obstacles to your advantage - bouncing a bomb off a wall can make it easier blow up a smiley face.
As soon as you get enough for the new wheels, buy them (all of them). Once you have all the wheels, buy the rockets (in order, so you'll get more points). Once you have all the rockets, buy the Hand Stand move. Keep doing hand stands while doing a backflip until you are good enough to do it without crashing (you should have about 15k+). Buy all the 'people', then keep doing hand stand backflips. Once you get good at it and know when to stop doing the trick (you can tell by the colour of the sky), you'll be able to get 2,000 points just for the trick, and the groupies double it. You should be able to get 4,000 points plus if you know what your doing.
Easiest way to get points: stay on the railroad track on the left side the entire time, and as soon as monsters start running at you, just back up (stay on the track) and they'll all come at you in the same line.
