Definitely needs improvement, but good first step!
The sprites were a bit shaky and fast, but they seem hard to do so I think that's just experience. The second and last blooper were pretty funny, but the first was a bit too similar to another flash movie and the third one doesn't make any sense to me (did the star fall down the pit or something?) The use of sound is also just a bit off at points, but the fact that it's your first movie and it has a select scene screen, load page, play button, credits and a replay button makes it better than many other submitted flashes. This one just is not the best thing I've ever seen.
