There are no HOS which makes this awesome in itself. The puzzles, and what to do, and where to go next is all extremely easy. I would recommend this game to a child or a brand new entry level gamer, but not to an experienced level gamer.
I found this game absolutely delightful! The puzzles were not so hard they couldn't be solved, the graphics are beautiful, and there are so many hints that just keep you going.... It is rather easy to figure out what to do and/or where to go next. I enjoyed it all the way to the end. I highly recommend this game!
