This game is sooo much fun you'll never wanna put it down! Seriously, There is no other game like this out there its definately up there with the greats like 999 and the professor layton series. But there isn't really any replay value like 999 but as far as puzzle games go that's pretty common. The story is full of twists and you'll find yourself guessing who the bad people are just to find out your totally wrong! So if you love puzzle games definately check this one out.
