I really like the way you can rotate the different faces of the cube and uncover new relationships, creating paths into dense regions that would otherwise be impenetrable. It’s a clever "twist" on Minesweeper-style deduction, and it makes exploring the board feel engaging and strategic.
I played for about 15 minutes before realizing that, even on the easiest difficulty, I had only made a tiny dent in the overall search space. That’s part of the design, of course. At any given moment, you’re only seeing a small fraction of the full board because of all the possible rotations, which makes the scale much larger than it first appears (x8, perhaps?).
Because of that, I think it could be interesting to experiment with smaller sub-cube sizes, maybe even something as compact as 3×3, as a way to ease players into the concept or offer a shorter session option. The larger scale is impressive, but for me this feels like the kind of game I’d enjoy sitting down with for 15-25 minutes at a time, rather than committing to an hour or more to work through a full board.
