I enjoyed it, but I think there are a couple of problems.
I didn't know what mission to do at the beginning of the game and had to rely on YouTube strategy videos. It would be better to present the things to do like other missions.
I'm a japanese,but I couldn't quite figure out “Izo families.” This is a surname that is not often seen in real Japan. It may be fiction. In this game, flowers could be offered to the graves of the Shimazaki and the Amazaki families.
The time-limited and refillable lanterns and the picking of locks that only allow four failed attempts are game-like specifications, but I think they are hard to play for the first time. The finite lanterns are common in other games, but the picking requires a knack for manipulation, and I think it is a killer for first-timers.
It was strange that the large Buddha statues and statues that were originally inside the temple were smaller and placed outside like Jizo statues. In actual Japan, such a scene does not exist, and Buddhist statues are installed inside temples.
There are other Japanese people besides me who are pointing out strange things in the comments that don't correspond to real cemeteries, but what they're saying is correct.
