Finished 2D Shooter

This is my finished 2d shooter project. I made the following modifications. 

1. Create a complete interesting, comprehensive, and coherent level.

2. Add multiple additional levels and tie them in to create a logical progression in your game. (NOTE: Each level should be unique in some way, such as different type of challenges for the player.)

3. Add custom music to your game. (NOTE: Custom meaning you created the music with a tool such as Garage Band or Fruity Loops. If you just swap out the music for another track you find, this is not considered a significant change ... though you can do it without it counting as a significant modification.)
