Every level is more challenging than the last

While most games make you sit through a slew of boring easy levels before ever making you think, this game makes you think at every turn. No two levels (so far) have even been remotely similar. My sole complaint is the hint system; Each hint shows you the placement of one piece. Most of the time Ive figured out everything except one thing, but I have to use several hints in order to build up to the part Im stuck at. Also if you ever get to a puzzle you are truly stuck at, and have no more hints, its game over. Youll have to delete the app and data, then re download it in order to start over, since there is no way to reset progress or obtain more hints.
