No! Don't do that!
NEVER use a gradient boxes! never! and NEVER use morphing tweens! ARRRRRRRRRRRRGH!
It wasn't really that original (the whole "whoopsie! where's my chord?" scenario), and you really should have used walking loops and not gradient squares and circles for characters. Good choice of music though.
If you're going to make another, feel free to use tweens in animation, but make sure you only use sqaures and such as templates to build the characters up on. i.e, actually draw the characters and animate them. There are a few tutorials to help you out on that one.
