White Haven Mysteries is a typical HOPA. It's mediocre in any sense possible. Why do I still recommend it? If you get it cheap enough - i.e., at a discount of at least 50% - you'll get yourself a fairly good deal if you like that kind of game.
# It has the standard game modes: Quick hint recharge and sparkles OR slow hint recharge, no sparkles.
# The graphics are good, but not amazing. The HO scenes are clear, and the objects are big enough to be spotted.
# It's quite short. It took me just 2 hours to finish it, and I read every journal entry and didn't skip a single puzzle.
# The story is nothing new. A spooky building, a mystery to solve, a mad scientist - standard stuff. The ending was a tad confusing, but I believe I understood it.
(Note: I can't say anything about sound or VOs, as I played it muted. Also, I finished it in one sitting, so I can't comment on the corrupted save file issue.)
