Have not played the original so can't compare them. Puzzles were just as hard as they needed to be. Great mechanics. Only two problems; Final area went for longer then I liked, and I wish it was scarier. Can't wait to play as Claire next.
Beautiful world and animations. I like the sounds. Puzzles are not so easy that its boring. Not so hard that its immersion breaking. I like simple controls. Nice moments of awe.
