The first actual sequel to Pac-Man by creator Namco but the third Pac-Man game on the market, Super Pac-Man mixes up the formula considerably – while Pac-Man is still eating his way through the mazes, he must first eat keys to open up gates to access the entire maze, which is filled with fruits and other objects rather than dots. The game's key differentiator is the ability to eat super pellets, which enlarge Pac-Man and allow him to eat through the gates, move faster by holding the Super Speed button and make him temporarily invulnerable (supposedly he is "flying," though he still must navigate the walls of the maze). Super Pac-Man's updates both complicate the game and arguably make it more approachable, as you can complete the mazes faster and more easily avoid danger.
