I didn’t experience any of the annoying banner ads mentioned in other reviews - in fact, I didn’t see any ads at all. I’m an avid escape game player, and I can’t knock a free app too much (not everyone is Haiku games), but I beat this game in less than 20 minutes. Not a lot of logic involved, and some of the descriptions of items basically give you the answer to the puzzles. This game could be good for younger children who like escape games.
