bootleg space invader assignment

Make a bare-bones space-invader game using Javascript and HTML-5. Use the sprites attached, add some fitting sound effects. Be thorough with code documentation, state what the purpose is for each class/section in the code. If possible, write all the code into a single HTML-5 file. Make as few additions as possible. When I say bare-bones, I mean BARE. BONES. Write the code as if you’re a high school student who can maybe scrape together a B- on a good test.
