Compared with the first game, Unravel Two really made some crucial improvements. The controls are finally what they should have been from the start and you can invite a friend over to enjoy the game together. It’s a shame this came at the cost of a less emotional story and a lower level of difficulty. The challenge rooms are there to compensate for the easier story but those are perhaps a bit too hard for most. That being said, it’s still a very enjoyable and beautiful game that deserves your attention. If you’re looking for a new co-op game, this one’s a perfect fit without any doubts.
