Code with minor alterations based on Attreya Bhatt's YouTube tutorial. See his repository at https://github.com/attreyabhatt/Space-Invaders-Pygame Original YouTube tutorial here: https://www.youtube.com/watch?v=FfWpgLFMI7w All audio files were sourced at https://freesound.org/ All art except for the laser was sourced at https://www.freepik.com/free-photos-vectors/game-background The laser art was my own work created in Inkscape
Attreya's version includes different art, and different ratios for his characters. This was all originally written in PyCharm using Pygame.
