This was such a fascinating entry. I can't help but talk about it by splitting it in two parts.
The first part of the narrative (everything leading up to the game) is just amazing. I simply love the art and the characters, the theme of poverty is depicted amazingly well. I even to commend the writing even more: this is an entry that doesn't really use flowery language, but it has no need to. The writing is to the point and manages to set the mood, develop the characterization, and advance the story in short straight-to-the-point sentences. I love it.
The story does begin to lose a bit when it comes to the game part though. Not because the game is absurdly complicated, but it is a bit much to follow along, I do think that more visual aides would help this a lot. Also I feel like the narrative focuses a bit *too much* on the game in the second half: while the game is obviously important, it would still be nice to focus a bit more on the characters and the real space they occupy at the same time, find again that atmosphere that was such a strong presence in the first half.
All in all, I can't wait to see how this VN concludes.
SPOILERS to follow.
Please forgive me one CinemaSins-style nitpick: I feel like believability was a little strained when the two characters were allowed to just go together to the bathroom to discuss freely their next strategy. Considering this is a high stake game run by the mob, it strains credibility that no measures were put in place to prevent this. I would have liked if the characters had found some more creative way to communicate between themselves *during* the game, and if the story had done a bit more with the situation of the characters knowing there was a mole among them. Instead, they reveal their newfound knowledge pretty much immediately, and not much comes out of it.
