This is puzzle game on the casual side which is not a bad thing. Puzzles are not very difficult but go well along with the chill and relaxing presentation of the game. The lack of a time limit to solve puzzles and the addition of an 'undo' button further emphasize the relaxing and casual nature.

The game is fairly short (2 to 4 hours) to complete the main missions but the game offers extra bonus levels after completing the main missions and there are achievements that can extend the replay value if you are a completionist. Overall, a fun, short relaxing game, thumbs up.
