The game has loads of Hidden Object scenes interspersed with cut scenes . The HOG scenes are rechargeable, giving the game some replayability, though I found the scenes and mini games very easy to solve. Each stage is scored, which gives you another incentive to replay levels to beat your score. There are more than 50 anecdotes about paranormal phenomena scattered throughout the game. The game takes you around the worlds to various mysterious and often enigmatic sites such a Stonehenge.
If you like simple and easy to solve HOG's this is one to download.

Also check out Reddit's Free Games on Steam (These may fluctuate over the week, so it's worth checking daily because there have been quite a few developers offering their commercial games for free during the lock-down - if you see a game, just open your Steam client and search for the game in the store; if it's still available free you'll see that they are 100% off, the site is updated frequently, so if a game is no longer available it's usually tagged with an 'Over' icon. Hurry though because these free games don't stay free long. Once added to your account they become permanently attached).

Hope this Helps on your Lock down
