I smiled and went "heh," but all in all there's a lot to be added here. For a 2nd sprite movie ever though, I do give major props.
Now: let's see some more sound effects, maybe some more music (to help set the theme of the screaming), possibly some plot/set-up? Those might be some good places to start, I think.
This was quite an enjoyable flash movie!
Your movie was random at the beginning. Very Good.
