Solid puzzle-platformer where you switch between a girl who can move in 3D (but can’t jump) and her shadowy 2D-platforming counterpart. Maybe slightly longer than it needed to be, and the difficulty curve is a bit out of whack (the puzzles steadily ramp up in challenge for the first two acts, then get much easier for a longish stretch before ramping back up again in time for the end), but a strong execution of this concept overall.
