I love all sorts of puzzle games and this one was a perfect fit for me as well as my playing style. I adore the simplicity of this game. The first dozen levels are merely introducing the various ways to work the puzzles, but beyond level 15, you need to concentrate and plan your moves with ever increasing hardness. I did finish all 50 levels in one day, so I was disappointed to see that is all there was, but I hope the developer will add more levels with even more twists and turns to keep us on our toes. I have now played through all 50 levels twice and may go once again because I enjoy this type of game so much.
