This was honestly a really good read/watch.
Centennial Case manages to present an intriguing plot with a really interesting mystery that crosses time. You witness how Haruka, the main character, manages to solve the mystery regarding the Shijimas utilizing her smarts and the novels written by an ancestor of the Shijima family.

Gameplay wise the game doesn't really shine, since the interactive bits of it are more of a drag than something really interesting. What I loved about this tho is that it's really unpredictable. Aside from chapter 1 I can't tell a single time I was sent into the "okay now figure it out" part having a single clue about what happened, but still managed to reason it out in the end with the help of the game. That's what a good mystery game should do and Centennial Case aces it.

While the acting is not the best around, it's not terrible either. The actors are really stiff and almost feels like you are watching a kids recital. Anyway the more you watch the more you find it normal so it doesn't really hinder the enjoyment of the game.
This doesn't mean the scenes are a mess though. There's actually a lot of care in the photography of every scene and there is no shot that doesn't hold significance to the story. Every line of dialogue has a clear purpose and there was no time that I felt like they didn't touch on a subject I thought deserved more attention, unlike some other mystery games out there (looking at you, my beloved Ace Attorney, you do this too often).

Overall a solid recommend. I found both my money and my time well spent.
