Pretty Standard.
Its pretty basic and a lot like other space shooter games. Its got a nice feel to it as well, with a little twist of robustness. I like it though, its really straight forward where you just move up and down and shoot the enemies for points. Good job, but next time work on some more added flare with this, the jellyfish idea got you the 8th star by the way, so I hope to see more creative ideas in the near future.
