Despite it's graphical style and kid like intrigue, the game is actually quite challenging, and doesn't insult the intelligence of the player in any way. I found some of the puzzle's too be thoroughly challenging, but not so much that it seemed impossible or anything like that.
Definitely not a story based game, but it has some fun humor and interesting things happen here and there.
Overall I am about half-way through now and have enjoyed every minute of this game so far, there is lots of secret sand things to do so check it out!
