It could be better, but still fun to play.
Well, you've definitely have the basics a good game down. You just need to bring it all together to make it more appealing to the player. I did enjoy it at first, but it soon became repetitive with no a whole lot of new stuff coming.
From a programming point of view, it might have been a good idea to have reset the velocity of the star after each death. Also, to make it a little more visually appealing, maybe the star could have rotated as it moved. As for the collisions, I believe you are using hitTestObject. (correct me if I'm wrong) You might want to look into irregular shape hit tests, as it would make your collisions more realistic.
