Way of the Samurai spinoff: Samurai Dou Katanakami

Hi there,

I've just found a a new Way of the Samurai game called "Samurai Dou Katanakami".

https://www.samuraidou.com/katanakami/top.html

It appears to be a spinoff, not Way of the Samurai 5, unfortunately.
From what I can tell, it's set in a parallel universe where demons exist in Way of the Samurai 1.
