I really liked the concept of this game but I had a hard time playing it because of the object grabbing mechanic. Maybe it's because I'm playing on a touchpad, but whenever I tried to pick up the blocks they would almost immediately fall out of my hands. I couldn't get past the long bridge section because I accidentally dropped it into the pit and then couldn't grab the object long enough to get it up the stairs. If there is a purposeful reason for the blocks falling out of the player's hands (moving too quickly, too close to the object, etc) I wish it was more clearly communicated. I did really like the highlight added to the blocks when you're looking at them, because it made it easier to see when you were able to select them.
