Nice submission.
I enjoyed this one! It was definitely long enough, and you obviously put some effort into it. Funny story line, although it seemed like you might've made it up a little as you went along. :)
The voices seemed a little slow, and you're right, the sync was off just a little bit. Did you set your audio to stream? That should fix the syncing problems and make it so you don't have to insert extra play buttons in the middle of your flash. If nothing else, at least change them to "next" buttons or something so they seem quite so out of place.
Otherwise, this was good, and I'm glad I got the chance to see it. Happy Clock Day!
