Not as good as the first one..
You kinda lost me at the end there... maybe you should have recorded more samples of him calling for his friend because the same one over and over just wasn't sitting well in my ears.
Then i think that ending it as such probably wasn't the greatest of ideas, not without a "to be continued" or anything especially, but i think there really should have been more to the flash.
Finally i'll just say how the jumpiness of the mouths is pretty cool, but the super lack of correct shaping of the mouths irks me.
Other than that, i like the storyline and for the most part, the script - i actually was excited to see what this one had in store for me, and i'm sure it'll be the same for the next one!
Keep 'em comin'!
