OK, I've clicked, dragged, wandered about, and just don't care. It's not obvious, not engaging, not interesting, and I'm out. I'm sure it must be technically wonderful, but I haven't a clue what it's supposed to be.
It's pretty obviously a game where the goal is to connect the same-colored squares on the cube.
Completely not obvious to me. Now that you've given me the clue it seems a reasonable game, although not my sort of thing.
