2d shooter completed

I added several modifications to the initial project. I added a custom soundtrack in the main menu as well as custom audio for the new "cat" playable character that i added. I also added downloaded music to the rest of the levels. There are 4 levels in total. The last 3 are completely custom and have their challenge to them. I added several new sprites and concepts that were not in the initial project, such as a leaf launcher. I also updated the menu to be very nice looking.
