I was liking Ghost Trick more in the beginning than towards the middle. Not that it ever became bad by any stretch but some puzzles are a little frustrating and other a little too illogical for my constricted mind to guess (actually only two things I couldn't solve).
Given I decided to play this a month after 999 and Professor Layton 3 I think Ghost Trick is the worst (although still like) but the first two felt so much better for me.
I played until chapter 10 and decided to give it some time or else I might not get into it again. I was thinking into getting Hotel Dusk but I may be a little tired from "visual novels" for the moment so I think they should wait a little.
Back to Ghost Trick I think I can understand why one would not enjoy the game as like I said, there are some puzzles that you have about a second to do the exact thing or else you fail and it can get very disappointing.
