It's sort of like the logic of sudoku, but instead of playing on a square grid, you play on a collection of overlapping unfolded dice (and filling in digits 1-6 instead of 1-9).
You can fill in the squares either by clicking repeatedly to cycle through digits or by typing the number on the keyboard.
You rely less on process of elimination and more on the knowledge that opposing faces of a six-sided die always add up to 7. You may find yourself imagining the cubes in 3D space, or you might learn how the opposing faces are distributed across the various possible flattened nets.
Technical suggestion: While it's great that you can type the digit you want when the cursor is hovering over the square, it would be nice if the player could navigate the board with WASD or arrow keys. I'm not bad at 10key, but trying to 10key left-handed while my right moves the mouse is quite awkward. I ended up playing the majority of the game by clicking.
Colorblind folks might have a tougher time with this one. Because so many of the die nets overlap in so many places, they're marked with little color tags. Unfortunately, some of the more complicated levels have so many nets involved that some of the colors look a bit similar. In these cases, the similar colors are usually kept fairly far apart to avoid confusion, but some of the later-game twists also affect spatial relationships and you might find yourself double- or triple-checking to make sure you aren't connecting the wrong colors.
It would also be nice to get some music added in. It wouldn't need much for how short it is. 1 or 2 ambient-sounding tracks would be really appropriate and welcome for this type of puzzle game. The existing background hum is better than nothing, but it gets a little unsettling and it's kind of ominous.
I hope that additional levels are added as DLC, I'd love to play more of this.
