I love this.
This Flash is so amazing. I was instantly hooked by the adorable frog sitting innocuously on his lily pad; I saw the pixel ball transform him, and I was ready for a masterpiece.
I enjoyed the different ways the frogs (also possibly the salamander and cat) danced, even though it was was repetitive. I had no problem with that, in fact, I think it helped make it more watchable. I was able to appreciate the cool backgrounds as well.
The choice of music was OUTSTANDING. I adored the song, and it helped keep the animation at a very reasonable pace. The only complaint I have is that, possibly in the interest of file size, the audio was output at a relatively low quality. I only noticed that when I listened the the song by itself, but it was much more crisp there.
