I liked the original "Mystery of Haunted Hollow". The graphics are relatively simple but as a point and click adventure game with lots of puzzles, I found it mildly challenging and fun. The second installment in the series comes out this Friday, Sept. 9.
According to the developer's Facebook page, "The Mystery of Haunted Hollow 2 will be released across the Apple Appstore, Google Play, and Amazon!" I asked if it would be available for Macintosh and they answered "yes".
