Great story-based casual mystery game, lasting about as long as it takes to read a mystery novel. With the help of your supervisor, Delilah -- with whom you develop an increasingly close relationship as the game progresses, but whom you never meet in person -- you hike, climb, and sometimes fall into a plot that has both Henry and Delilah growing more and more worried about their choices and their futures. Aside from a couple of the usual red herrings one finds in mystery stories, the gist of the tale becomes clearer as you progress. Having played through the game only once, I can't speak to the value of replay. (With the mystery solved, I don't see much point in replay, for that matter.) You do wrestle with some matters of personal choice and dilmena, but in the end it does not seem to matter much. One factor that kept me intrigued as the game approached its climax was the thought that Henry would finally get to meet Delilah in person. In that regard the game might feel like a bit of a let-down. After all, the mystery is just the vehicle through which Henry and Delilah come to know each other and grow emotionmally connected -- and come to know themsleves a bit better as well. That is the true heart of the tale. But once the mystery is solved, our players exit the stage with a limp rather than a roar, although possibly a bit more humble and slightly wiser. Aside from that final-chapter fumble, it's a pleasant experience and well worth the sale price I paid.
