Mystery Lighthouse: puzzle app game for iphone, ipad

Mystery Lighthouse is  not a new puzzle app game. It came out about a year ago. It's similar to Myst. If you haven't played that, well, you simply must do so!

 Mystery Lightouse: you must walk around the island and figure things out, pick up tools & coins and ultimately find out what happened to your uncle Augustus who is/was the lighthouse keeper.

You can solve the whole mystery in about 1 - 2 hours.  My son, who is 11, really liked it.
