I got my background sound effect from this website (http://strongholdgames.com/time-n-space-soundtrack/ ) which allow user to download for free. As this is a student project, i wish that by using this sound effect will not bring me any plagiarism issue.
I download the sound track then bring in to Adobe Audition to edit and make it able to loop .
I download my game sound effect from the 80 games space invaders game sound effect which i found from this website (http://www.classicgaming.cc/classics/spaceinvaders/sounds.php). Basically i downloaded the shooting sound and the explosion sound effect.
