C'mon now.
As a flash movie:
Graphics: Good stuff
Sound: Good stuff
Originality: Not so good stuff. Any one can take a joke an animate it, but to think of your own and then animate that. That is where true talent lies.
Now. Whether this is, or isn't an attempt to spread your beliefs is not really to question here. What upsets me about this flash being on newgrounds is not its content as of the religious standing. But more so that NG is a place to share you art with others. All you've done really is sparked many arguments, further spread a one line mediocre joke, and show us that you can animate.
My suggestion (since this IS a review NOT a place for personal religious opinions): Think of some new material, then put your skill to that. Then you will join the ranks of the greats. Good luck.
