Iwatani wanted his game to appeal to a far wider demographic,
which led him to add both the maze element of the game as well as the‘kawaii' ghost enemies(Blinky, Pinky, Inky and Clyde).
This was a deliberate choice Iwatani made very early on in the game's development so that,
as he said,“they weren't all just chasing after Pac-Man in single file, which would have been tiresome and flat.”.
