Reality Show: Fatal Shot Collector's 

This app is a special edition of the Reality Show: Fatal Shot game. The differences between this game and the standard edition is that you have access to additional features, like an extra chapter, a built-in strategy guide, and some quality screensavers, wallpapers, and soundtracks.

The storyline is identical with the one from the standard edition of the game. A grieving woman asks for your help after her husband was killed on the set of a popular TV show called Fright Reality Show. Your goal is to use your detective skills and unravel the truth behind the mysterious murder.

Your investigation begins in your office when the widow approached you. You will visit dozens of locations filled with clues and mini-games, interact with various characters, etc. Your progress is automatically saved and you can use the built-in strategy guide whenever you get stuck in a location or while solving a puzzle.

The only disadvantage is that you need to restart the app in order to apply display settings changes. So, you need to shut down and relaunch the game to toggle fullscreen or windowed mode. However, this aspect isn't a big deal to me.

All in all, I think you should give this puzzle game a try. The app brings you a storyline that's filled with many plot twists and interesting characters, has nice graphics, and offers you plenty of challenging puzzles.
