I enjoyed this game the first time, when I played it on my PC. There is nothing new or interesting for the people who have played the PC game already.
The game often requires you to make incongruous leaps of faith with pieces of evidence, as well as what location to visit at what time.
If you want to play this game, crank your DS brightness up so you can see things, click on EVERYTHING, try all the tools for each piece of evidence and good luck. It's basically a trial and error process. Sometimes the intuitive thing to do is not what the game wants you to do.
Overall, watching the show is more interesting than playing the game.
