Papa Louie: When Pizzas Attack! is the first installment in the Papa Louie game series. It was developed by Flipline Studios and released in 2006. The game consists of 4 worlds with each world containing 3 stages. It is the first platformer in the Papa Louie series (followed by Papa Louie 2: When Burgers Attack! and Papa Louie 3: When Sundaes Attack!). In the version of the game that is developed specifically for Kongregate, there are also 36 Kongregate coins that are scattered across the stages (each stage having three Kongregate coins). Collecting these coins will unlock the Hard "Gourmet Kongregate Supreme" badge, which is worth 30 Kongregate points if the player of this version is a Kongregate user.
