Very challenging!

I enjoy a hard puzzle. If a puzzle is easy to solve, it's not very gratifying to solve it. I have to say these puzzles are not at all easy. I am now on level 10 of the "easy" group. There is nothing easy about this. I would recommend the app developer come up with new names. "Super Easy" and "Easy" have so far been "Hard" and "Difficult".
