Not bad at all
You know, this "test" is better than the majority of "serious" submissions on Newgrounds. And that's not praise for this flash, though there is nothing wrong with it. The graphics and animation is a little clunky, the sound is made up from too short, repeating samples and it ends abruptly, but it's amusing and has more than 5 seconds of thought and effort put into it.
If this is a first experiment, I'm interested in seeing a bigger project.
