Could be good
All I can say is that this has a lot of potential, especially if you take your time with it. Drawings and sound were good but I have to give this a 0/5 because the portal isn't a place for previews, coming atractions, demo's etc. Tom made the Alpha section of Newgrounds with better tools for the reviews to criticize an authors work.
Like I said, has a lot of potential, I hope to see it, but please don't rush it like some authors do, if you do that te quality of the flash often gets hurt. Take as much time as you need to finish it to the point where you are happy with the result.
