Nice, simple concept, but the grab mechanic is definitely buggy and you can launch yourself with the blocks. Since this has been mentioned before, I think it would be more productive to talk about how there's no division between the level parts in any way, so you can just reuse all of the past objects, meaning you can just beat the levels with the big plank.

The menu and directions are clear. Love the concept, but the grab mechanic is completely broken.

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.
