Fun little solo experience. I find that solo games tip somewhere on a "game" vs. "guided journaling experience" scale and I'd put this pretty solidly on the "game" side. You could journal your experience if you wanted to but you don't need to and the game is going to move along without you having to be at all creative to advance the story. Maybe the downside to that is that you're going to be on rails, so if you want to free roam you're going to have to kind of hack it in between game encounters. Just depends on what you're looking for from a solo experience. I did find my enjoyment was enhanced by taking a little extra time to envision the scenes the game was putting in front of me and to take advantage of some of the "fluff" that the game offers, but it's also something you could just roll your way straight through and still have an interesting experience. I've never had much interest in either anime or Japanese history but this made me want to research shoguns a bit, so bonus there too.
To be honest my first playthrough ended in kind of a stalemate situation where (if I was interpreting the rules correctly) I could not die but yet I was also stuck needing a series of improbable rolls to proceed which, technically, I eventually would have made if I kept trying long enough but it felt a little unsatisfying so my character just gave it up. I guess if I had one criticism it's that... I wouldn't mind if the game were just a little more lethal so there was more dramatic weight behind the encounters, but obviously with a solo game that's someting you can adjust to your own taste. I'm just one of those weird people who gets physically uncomfortable when I start making up my own rules, I guess I just don't like to color outside the lines so I'm reviewing it as written.
That being said, it's well written, easy to understand, the art is attractive. All in all a great package. I used PWYW to try it out, and definitely went back and purchased it, I for sure got my money's worth.
