obviously, I love the color-scheme...
I like the idea of switching between 2 modes of playing after each point - and the music and the graphics was a good starting point. but was there really nothing you could do to alter the actual gameplay? I feel like that part is missing.
also, you should really switch the colors of the the score texts as well. that should be fairly easy, no? it really rubbed me the wrong way that it stayed the same ;-)
