How it feels

A meditative and cerebral experience where you piece together a fragmented world through logical deduction, feeling both calm and curious as each solved puzzle reveals another layer of narrative.

What players say

Players say the nonogram puzzles are well-designed with a steep difficulty curve, but the visual novel story is mediocre. The game is short, around 4 to 6 hours, and the music can get repetitive. Some players report crashes that lose progress and a few puzzles that require guessing.
