This was a pleasant surprise of a game! It is a deductive mystery that's basically a text adventure with some small pixel art illustrations, but it's in a really unconventional format. You get everyone's dialog with one person and you have to sort the dialog snippets, both related to who said that and in what order. So it's like a grab bag of dialog that you put together like a puzzle, to solve the mystery related to the disappearance of a child in 2010s South Korea. Everyone lies at least once (the game says this upfront, it is not a spoiler). This sounds like a metroidbrainia, but I think it's better classified as a deductive mystery. it's not entirely made up of knowledge-based unlocks - in multiple places your progress to get specific dialog snippets is actually gated by having to find keys. But you get the keys in a nonlinear fashion by piecing together various other snippets, so I'd say it's metroidbrainia-adjacent and could potentially appeal to the same audience. You really do need to like deductive mysteries and text-focused gameplay though. The game is quite short and I recommend setting aside 2-3 hours to play it at a stretch. I tried it, and then set it aside for about two months (I was dealing with a very disruptive house repair and then move) and when I resumed it, I needed to reread everything because you're supposed to remember a lot of small details and keep them in mind. It took me overall 3.5 hours this way. The actual mystery is interesting and not what I expected! Without spoilers: I really liked the focus on family and children, and it was intriguing to find something with these themes that was not particularly cozy (I like cozy games too, but families shouldn't only be equated with cozy themes). I recommend 100%-ing the game because then you get an additional reveal. I also liked the art! The music started to annoy me after a while, so I eventually turned it off. I would love to play both more from the developer and also other mysteries in this exact format. There are three more games by the developer (Somi) and I think all of them are text-heavy investigation games with different formats, I hope to get to playing those eventually, too. Technical details: I played on the Steam Deck docked to the TV and with a PS4 controller. It worked well, but I'm not sure it would work so well on the Deck's own screen because it's just a lot of small text that you scroll around. It probably makes more sense to play it with a mouse than with a controller, but I prefer a controller (this one has a touchscreen too). __ Source of the game: Bought with my own money, in one of the big quarterly Steam sales. I think it's worth full price though, it's very unique, a good experience and just the right length for the gameplay.

Recommended to its audience, but it was not personally for me. This was my first time playing a game like this. You reconstruct fragmented conversations, determine who said each line, arrange the dialogue in the correct order, identify keywords, unlock further testimony, and use deductions to solve the case. I found the concept novel, but the actual detective gameplay was extremely frustrating for me. I did not enjoy meticulously combing through dialogue, testing arrangements, and trying to determine exactly what the game expected. I eventually used a guide, which transformed the experience into a guided interactive mystery. Played that way, the story was interesting enough, the four hours passed surprisingly quickly, and I enjoyed gradually seeing the full case come together. However, using a guide also meant bypassing the main thing the game was designed around. I respected the logic and structure of the puzzle, but I did not enjoy performing that logic myself. I do not regret playing it, and I appreciated experiencing something genuinely different, but it was firmly a one-and-done curiosity for me.

I went in completely blind, I regret nothing. A short detective/puzzle game with really cool mechanics. It basically guides you to check on some pieces of text again and again, this works really well as it allows you to piece the story in your head and, frankly, makes you feel not-so-stupid, pretty smart in fact, wow look at me connecting the dots before I get the answer spelled out for me. I found the mechanics quite quick and easy to figure. On top of that: very good writing, the story makes sense and I liked the message the game delivered overall. Cool attention to the details on speech patterns of each character. I loved it.

Short but sweet investigative game (took me 3 hours to 100%) with a heartfelt and satisfying storyline. The large textboxes can be a little overwhelming, but the minimap helps a lot. Tip: Date entry is MM/DD.

Make sure you start very, very comfortably, and don't bother looking at any reviews about the story, because you'll finish it one sitting. It was confusing at the start but you get to see your efforts slowly bring into view the actual solution to the jigsaw puzzle. The writing not tripping up on itself at any point is genuinely so impressive given just how big it gets.
