I enjoyed the story line, but there were definitely fewer puzzles in this one, even including the bonus puzzles, and that's just total number. Less variety in the puzzles themselves, many repeats within the game. The puzzles were way easier than last time. Like the last puzzle agent, unanswered questions a plenty to keep us waiting for the next installment.
What I really didn't like was that the game was clearly shorter in addition to being far too linear. I really liked the exploration that made the previous game more in the adventure genre. Ironically, despite the addition of 2 new characters, I feel like the majority of the characters were completely ignored, and many were just cut or only got a select few lines.
