This is a comedy that doesn't take itself too seriously.
It's not trying to say anything about feudal Japan, though it is set in feudal Japan. I feel it is also of dubious historical accuracy.
I liked the English haiku generator. You get to keep generating poems until you get one you like, and they range from rather pretty environmental metaphors to silly-funny lines like calling the royal guy who sentenced you to death a blockhead.
I liked the archers who have really bad aim.
I liked the bear whom you can optionally feed to get past, instead of killing.
I didn't like the fat/thin jokes about two samurai foes. >amusing suggests throwing a rice ball at them which will get you some nettling about how they behave upon seeing food.
In the end, the game takes itself so un-seriously that it recommends to you a USAmerican Antebellum novel about sad confederate soldiers.
It to me held a lot higher regard - and perhaps even a bit of cleverness - before I saw that. The twist makes perfect sense for the game already. The literary reference added nothing but disgust.
Should've just shamelessly stolen the twist and not credited it, tbh.
