I was in the 16 million range, too, and I had just run through the PC version so I was fresh on the levels. 20 million is going to be tough. It's also going to be hard to finish all of the challenges - the last few are an absolute bitch. I also played about 2 hours of Peggle Party and damn is that fun. The only crap part is that you need to beat single-player to unlock all of the characters.
