This game has an interesting relationship to mimesis. It’s very much a game of two halves. The first part is a puzzleless tutorial about following cultural rules; the second part is a series of puzzles with little cultural rule following (other than observing the priest’s ritual).
In the initial tutorial section at the inn, the player’s action is entirely dictated by what is culturally expected of the samurai character. For example, the player must take off their shoes before entering the inn. The game throughout is richly researched, though written very much in an edutainment register.
In the second half, the player does three of what Roger S. G. Soralla, in his seminal essay “Crimes Against Mimesis”, called “Puzzles Out of Context”. The player has to solve a logic grid puzzle, a Nurikabe puzzle, and a maze with room names all alike (this isn’t a spoiler, the game’s main page explicitly warns you that these are coming). To Garry Francis’s credit, all three puzzles are somewhat embedded in their setting, though their presentation in each case quite literally takes you out of the game. In the two logic puzzles, you go away from the game and fuss about in an abstract grid and then go back to the game and enact the solution; in the maze, you’re encouraged to make a map. Map making is a time-honoured adventure game tradition, and one of the game’s goals is to teach players somewhat to play adventure games, so I can’t really begrudge this one. However, the overall effect is to repeatedly step out of the story and think as-a-player, rather than as-the-character. And this is in sharp contrast to the initial, more setting-grounded, section.
In the second half, the social rules have mostly been forgotten about, the player needn’t remove their shoes before entering any of the huts (though perhaps those rules don’t apply to commoners).
There are a lot of period-appropriate details in The Samurai and the Kappa, and the game invests the most detail on three of them: the specificities of the strange myth of the Kappa, Kami temple rituals, and inn-based child prostitution. The first two are intertwined with the game’s puzzles and plot and make the game a distinct experience. The third is a period detail that the author was especially interested in exploring but has no impact on the plot or puzzles, though maybe we can say that it is used as a way to teach new players how to use the parser.
Both halves have their merit, but tonally they make for an unbalanced experience.
