Chroma Cabbie

In Chroma Cabbie, you're are a taxi driver tasked with picking up troubled passengers who happen to be aliens. Talk with them, and find out their feelings by their change in color. Drive around and deliver them to their destination as the right color, and maybe help them with their troubles. Be careful though, as there is always something going on with the roads in this city, and if you're late your passenger will bail on you.
