Is that it? Nothing really happened.
You shouldn't have submitted this as it isn't the finished version and I feel that demos/trailers/previews/unfinished work don't deserve to be submitted to Newgrounds as they are not the finished version, you should wait until you finish something before deciding to submit it.
Demo/Trailer/Preview/Unfinished Work rant over.
At first I thought that this was going to be a good trailer, as you set up the very start really nicely and the music went really well with it, but in the movie nothing really happened at all, it was eventless so there was nothing to generate any interest and the trailer didn't really tell you much about the game that you were making, just that it was about monkey's escaping from some sort of laboratory. If you were going to bother with a trailer you should have had something interesting and worth watching happening in it, instead of just showing, a lab, some monkeys and test tubes.
