Love Detector Face Test Game is a fun iPhone app developed by Tim Denyer. As a lifestyle game, it aims to entertain users by providing a simulated love detection experience. It is important to note that this game does not have any actual photo detection or recognition capabilities.

The game is simple to play. Users can either take a new photo or choose an existing photo of themselves within the game. They also have the option to add their name, although it is not mandatory. Before starting the scan, users can long press the scanner needle to pre-select the game result as either "like" or "love," or they can wait and let the game choose randomly.

Once the scan is initiated, the scanner lights up and scans over the photo, followed by a pre-selected or random game result. The game will either indicate a "like" or "LOVE!!" for the player.

Please note that Love Detector Face Test Game is purely for entertainment purposes and should not be considered as an actual love detection tool. It is a lighthearted game that aims to bring some fun to users' lives.
