This song was originally used for the background music of the final boss for a game I recently finished kind of mimicking the game-play of Space Invaders. It's on yoyogames.com if anyone's interested in looking for it. It's not a flash game so I couldn't submit it here! :( It's called Pix-Vasion.
Please contact me if you would like to use this in a project. We can discuss the details.
