No challenge whatsoever
Well, it was rather challenging to fit pieces together that way I wanted them to. The connection process is pretty hit-and-miss. Manually sliding panels were more of an annoyance than an obstacle. Gear activated panels were pointless as we were already planning on attaching all the gears there anyway. The only obstacles were the pre-placed gears. Even though they could only move one way, all you had to do was place two small gears instead of one larger to move it the right way. There was nothing new throughout the entire game past the tutorial stages.
