You have done a very rude thing. :(
Don't submit unfinished things! Normally, I hate to see parts and bits of flashes and games come thru. They're parts, not finished items, and Newgrounds is for finished items.
What you have done is worse. This is cool. I want more. I want to know what happens. I want to see the end. I was impressed. THEN you stopped it WAY TOO SHORT. That's like making an awesome dinner and then taking it away with only one bite.
So not only did you err in that you submitted an unfinished item, but you also put thru a painfully small taste of what could be a grand finished product, but you'll also now be stuck with a forever unfinished bit on Newgrounds- because you'll submit the finished item as a separate item, not replace this one.
That's too bad. Really. :\
