The full version of Natalie Brooks: Mystery at Hillcrest High sprawls over ten chapters, which should each take around thirty minutes to complete. The twists, turns, and complicated puzzle-solving make it a satisfying download for any player who is inclined to enjoy object hunting or Nancy Drew-style super-sleuthing. Be warned, though, that Mystery at Hillcrest High has absolutely no replay value. Solving the mystery is lots of fun, but once you've beaten it there's no reason to play the game again. You'll probably find yourself yearning for Natalie's next adventure instead.
