Could have been better.
The movie was so-so. It wasn't bad, but it wasn't really good either.
One of the things I liked the most was the style of the drawings, I always like this kind of movies that look like they are drawn and colored in paper. In this case you combined two styles, the one I just mentioned, and normal flash drawings/animations. In my opinion this doesn't look good at all, I think you should either draw the whole flash in one way or it may look a bit odd.
The music's quality wasn't very good, I'd say it was the worst thing of this flash. Even if someone chooses the right music, it can be ruined if the quality isn't good, because it's something essential. What can I say... At least there WAS music.
And then the story. It wasn't too complicated, but at least it was well executed. But I expected it to be longer, because it doesn't really explain why the number 13 was missing and sold out everywhere.
Overall I think you got talent, maybe if you get a good plot and follow some of the aforementioned tips you could make something great.
