Beat it in about 30 minutes! Very simple, and a very cool interpretation of the theme, kind of like how Witch Core interpreted it.
Rarely play this kind of sudoku-like game, so figuring out the optimal strategy wasn't easy, but patterns and concepts started to click as I went further. Some puzzles were easier than others and/or more susceptible to brute force, but overall there were more than enough times when you had to figure out the right move instead of just fill the numbers by feel. Black and White aesthetics are definitely my thing, and the music was pretty relaxing and fitting for a puzzle game.
Not much else to say - a simple, clever game with just the right mix of both. Congrats on finishing the jam in just 8 days!
