An app developer created a match 3 game called Alien Invaders. They needed a complete set of game sprites for the app including six characters plus a special character, a set of buttons, arrows, and stars, and two backgrounds, one for the main title page and one to be used as a background on the game page. All of the game sprites had to be saved as specific sizes and files and had to have specific file names to work with the coding for the system.
