The idea of a japanese-themed style for Demonic Digestion came suddenly, and I ended up sticking with it not knowing exactly why.
Being an anime & manga nerd and a karateka, I've always been passionate about Japan and its culture. Because of this, I didn't have to dig into deep research before being able to pull out a convincing style, that gave the game a distinctive feel.
Also, there are already some well-known games that heavily reference a traditional japanese style, and I was especially influenced by Okami and Zelda the Wind Waker.
Here are the first concepts for our game:

But for me it wasn't simply a strategic move: I had a lot of fun quoting Japan's traditional symbolism and its repertory of colorful demons, called yokai. I tried referencing existing yokai as much as I could. For example, the boss from our game explicitly (and very roughly) quotes the gashadokuro demon as it was depicted by Utagawa Kuniyoshi:

Here are some other ukyo-e that show where some choices in our game came from:

I hope you enjoyed this small behind the scenes of Demonic Digestion, and also I hope I tickled your curiosity towards some aspects of Japan's tradition :)
