Though the puzzles aren't that difficult and the gameplay is mostly linear, I didn't care because of the visuals and sound. In fact, to me that added to the charm of this game. I loved the seaside atmosphere and it was refreshing to move comfortably without any long delays. Even the puzzles that looked complex at first ended being pretty simple to do. There isn't much of a challenge here but so what, this game takes my #1 spot off all I've played so far.
This game was giant and I can't imagine playing it on any high difficulty level. About midway in I started clicking the 'Hint' button just to transport to get to the next area quicker. The main puzzles were great and unlike anything I've ever played before. They will make you put on your thinking cap although the hint and skip button will keep you from ever getting completely stuck. I recommend playing it on the easiest level to keep it moving along at a comfortable pace.
