"We've spent 20,000 years together with dogs: molding them to understand us better and to adapt to our world," said Cancienne. "I think that's what's interesting to me about a dog alone in a city."
As you see, Princess greatly inspired the plot and look of the game's main character. But she wasn't the only influence for Cancienne, who noted how the story of the famous Japanese stray Hachiko got him to start "wondering what [the world] all looked like from a dog's perspective."
"I think video games have a fair bit of potential in getting people to try out other perspectives," he said, so he got to work and used Princess as a model for reasons "partly out of love, partly out of laziness," according to the developer.
