Concept art
The game started out as a similar but deeper game called "Pac-Man Adventures", featuring involvement from animator Don Bluth, who had previously been hired by Namco to work on "I-Ninja". Concept art from Bluth for the game included many different alien and creature designs, as well as the protagonist from the "Dig Dug" games and expressions for Pac-Man when he "loses control", implying a type of gameplay mechanic not seen in "Pac-Man World 3". For unknown reasons, the game was scrapped and later reworked into "Pac-Man World 3", with Bluth no longer involved.
