Really cool
Woah... how INTERESTING! This flash has a really unique feel to it. The character design is near professional quality, which I do not see on here often. Also remarkable is that you kept up the quality throughout the whole (long!) piece. I watched the movie before reading the authors notes, so I didn't know about how you took turns on it. But I definitely noticed how animations were rarely recycled, props were not recycled, and how the setting constantly changed (thus requiring loads more art!)
In the beginning, I felt it moved too slow and I was tempted to stop watching. However by the middle I sort of "got" what you were going for, and I was interested to see what the heck you would throw at us next. I wasn't disappointed, since you gave us cyborgs, zombies, and took us to outer space and back! The multiple natural ending points that DID NOT in fact end the flash were really amusing... I mean, the salt thing? THE ROBOT ARM GRABBING HIM? Going into a secret compartment after returning to real life, etc? Those parts were hilarious. I also liked the little digging underground scene. It added in some "parody" factor.
So overall very enjoyable; I am still impressed at the length and the dedication it took to keep going with it. In your next flash, I would suggest concentrating on making the action flow quicker and more smoothly, as another reviewer said. You could also play around with adding more in-betweens, although I know that was not the point of this particular movie. Good luck!
