2d Platformer

This is my 2d Shooter project. 

Proposed Modifications: 

Create a complete interesting, comprehensive, and coherent level.

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.)

Modify the in-game GUI in some significant way
