Got a shot at my sister's copy and spent quite a bit of the day playing it. I've got 35 out-of-sequence puzzles under my belt, and I'm enjoying it pretty well, even though I don't think I'd enjoy it quite as much if I'd paid for a copy of my own.
Thing is, I'm in love with the puzzles (well, maybe not the slide puzzles), and the art style is lovely, but the rest of the package is...a bit irritating, actually. The story itself is a bit bland, everyone besides Layton comes off as a moron or a jerk, and the soundtrack gets old mighty fast. Still, the puzzles make up for a lot. Only what, 90 or so to go?
P.S. Does anybody else hear Layton's voice as Raiden faking a British accent?
