I'm guessing this fits the contrast and protect it themes. Though as someone who didn't play with virtual pets, there's no clear instruction what to do. And given the nature of the graphics style, I wasn't quite sure what some things were. I won the slider game about 30 times and only made 2 gold, never got any from the mirror game. Don't know if there was another method to earn gold but ultimately died because i couldn't afford anything.
