There's an easy way to get unlimited everything without paying or making more accounts. I pretty much just play it to get the highest score out of my Facebook friends. With unlimited lives and unlimited power ups its easy.
I love how I managed to get a high score of 74, then manage to crash into the first pipe on the next play. I've almost reached my highscore twice, but the more I play the harder it seems to get past 10! Aaargh! Trying my other thumb now.
