Hey, this is a cool concept. It reminded me of those maze boards that you must make the ball get to the end, without falling on the holes.
But for me the game is a bit slow, it lacks some physics as well, it would be nice if when the box is at the edge of a cliff, it would tip over and fall, instead of staying there stationary. Also when if whrn rotation it wouldn't stop in place to start going in a different direction, but would have some momentum of the previous movement.
