I've gotten through about 23% of the game so far, and I love it. The puzzles are really awesome. The combat got bad reviews but I actually enjoy it. Same thing with the motorcycle parts.
The one thing that might turn people off is that it is pretty short. I mean there's replay value in the different difficulty modes, unlocking all the costumes, and getting all the Achievements, but it's maybe a 6 hour game at most. Personally that's not a problem for me because I have a short attention span for games (except rpgs) and that's enough to have fun with.
