A stylish little noir visual novel that only took me around 15 minutes to finish. The story is VERY short but intriguing and the unique diorama-like art style really stood out. Definitely worth checking out, especially since it's free (at the moment of this review).

It may be very short, but this visual novel has some interesting and unique traits about it. The fact that everything you see was (most likely) made in Blender, as well as the semi-interactive sections in some chapters, makes this game worth playing. Plus, the noir vibes are a welcome bonus.

short n sweet, minimalistic mystery novel, but the division of the chapters doesn't make much sense though

I booted this game with zero expectations and i have to say it is not for everyone. Basically it is a interactive sort of book with little to no gameplay but the story, the story is fantastic. i would recommend this game to you if you like detective/ mystery books or shows and deep mystery stories with zero explanation if you like these things then please find 20 minutes to spare on this amazing game. Bonus-You get the badge for completion if you just finish it.
