Hidden object games are best-suited for desktop computers, mainly because a large part of the gameplay involves searching densely-packed, highly-detailed scenes - a task that's clumsy to perform on a smaller screen. Moreover, the complex puzzles of adventure games are also better-solved with a mouse than with touchscreen controls. Haunted House Mysteries for iPad is a nice-looking game that suffers by appearing on an inappropriate platform.As so many hidden object adventures do, Haunted House Mysteries begins with a terrible tragedy. A famous archaeologist and his family are murdered in their New England vacation home, presumably because of a rare artifact being kept there. Years later, Nancy, a young graduate student writing a thesis on modern-day superstition, is called to the home by her elderly aunt. On the surface, the invitation is for Nancy to enjoy a few days' R&R, but she soon discovers her aunt's true intention is for her to investigate the site's alleged paranormal activity."Haunted House Mysteries was obviously made by a team of talented artists, since from the first spooky scene it makes a good impression. Nancy and her aunt are sharp and attractive by design, and so are all of the game's locations. (I'm fairly sure the exterior of the main house is the Norman Bates Psycho house.) The game also sounds pretty good thanks to a nice music score that effectively augments the lugubrious Victorian interiors.
