Very nice
What started out as another little flashie trying to get by on a cute style and song turned deep, very deep.
At first I was set on giving this flash a 3/5, since it was no different than the thousands of song flashes on Newgrounds, and executed worse too.
However, this was much more than that, as it soon became a beautiful metaphor for the standardization and lack of freedom in today's educational systems - and all of society.
Your use of the audio to continue a logical flow is rarely used, so while the visual scenes could not be more different, more separate, the continuing song helped link them to a common purpose.
Nicely Done.
