While Valet Hustle initially seems like a standard Diner Dash-style game in which you park cars and pick up customers outside of nightclubs and restaurants, developer Factory Games took an interesting approach to the story for its debut iPhone game: both of its playable characters, Ren and Akira, are gay.

The two protagonists both have wealthy Japanese businessmen as fathers, and both were expelled from boarding school after they were caught kissing another student of the same sex; upon hearing the news, their respective fathers order them to take over the family's parking valet company. As players progress through the game's levels, they'll learn more about Ren and Akira's personal lives.

The game features an electronica soundtrack (with an option for custom tracks), 3D cutscenes, and six levels set in Tokyo and New York. As an added bonus, Factory Games is donating a portion of the proceeds from Valet Hustle sales to the Human Rights Campaign, which is devoted to campaigning for lesbian, gay, bisexual and transgender equal rights.

"It's cool to have been involved in the creation of Ren and Akira, two characters who triumph over prejudice by simply being themselves," says Lulu Magdangal, who served as the story development consultant on Valet Hustle. "I can only hope that Valet Hustle is the start of a trend and more game companies embrace both the gay and lesbian communities."
