While a good game, I felt that Monkey Island 2 had inferior puzzles to the first game.  There were several rather un-intuitive ones, a lot of backtracking, and a few that required split second work.  Time based actions in a puzzle game are annoying at any time.  Trying to figure out which action to do, and the exact second to do it in is a real pain.  It felt more like they were using a new feature of the game rather than something that made the game better.  But overall enjoyable and the ending is rather surreal.
