Biggest complaint is the lag while dragging the pieces; an adult can work around it but not a child. Also dont like what many of the objects are called. Motor for motorcycle, plush toy for a Teddy bear, I can go on. Sure it may be correct but its hardly common English in many cases. Lastly dont like that theres a cheat button.
