I like the idea of it - a whole slew of layouts and a variety of tilesets. But the execution leaves a LOT to be desired. The settings are sloppy or just seem unfinished. There is no sound slider -so you cannot turn off the horrible background music unless you mute your PC. You can either have sound effects on or off - again, why no audio slider? There is a list of layouts from other people and there seems to be no rhyme or reason as to how they are listed. Easy, middle and hard all jumbled together. A mid-difficulty puzzle I selected was way to simple and easy, there was no difficulty to it at all. Who determines the ratings. Also, there didn't seem to be a lot of puzzles listed. There was a link to download "more" but it was unclear whether it was more layouts, more tilesets, more background themes... just one download button, and even when clicked it, nothing happened. Again, good idea but not well executed, in my opinion.
