Well...
It was a good start. I liked the graphics and the music you have. I think you could have made something a bit longer though. Also, this could use a main-menu at the beginning and a replay button and the end (I'm staring at a blank white screen here, at least give me something so I don't have to reload it).
This looks like the beginning of a series, brush up on you're work now and I'm sure it'll be something great.
