Note that the bottom right corner's not yet connected to win the game. That's because I wanted to get a shot before the big "you won" dialog showed up.
As you can also see, the game gives you a running total of how efficiently you've been playing. If you rotate a piece more than the minimum necessary, it'll ding you for it.
Scores will be based on some byzantine combination of time, efficiency, and difficulty. ContinuityBox is actually a little easier than "classic ConFusebox", so you won't get the really big scores in this mode.
