It's a true Professor Layton game, through and through.

Good conclusion to the prequel trilogy, decent puzzles, great characters, and very charming all around, although both the stories and the puzzles drag in the middle.

It's biggest flaw is that it dumps all of it's lore on you in the third act and doesn't elaborate. It's horribly unbalanced, especially when compared to other entries in the series that sprinkle the lore throughout and then tie it up at the end (such as Unwound Future and Miracle Mask)
