The controls are way too slow. Pieces don't move when dragged - you have to hold down the mouse button and wait for the piece to lift off before you can move it. If you need to rotate a piece 90 degrees counterclockwise you have to click and wait, click and wait, click and wait. It takes 1 second to see where you want a piece to go and then 10 seconds to get it there.
The first pants are SO HARD. I have got the shell into the spoon to the left of the gap at least 20 times now. Then either I kick it too softly or too hard, and it rolls down or bounces back down.
