Ori and the Will of the Wisps is a fantastic continuation of the first game. All of the new mechanics, as well as the old ones that were brought back were all carefully planned and thought out to fit in with the level design. Once you have been given the main quest of finding the wisps, you have pretty much all of the materials needed to go anywhere in the world you need to go.
When playing, I constantly found myself saying "Woah, that's awesome!" It's like the developers took everything that made the first game great, and expanded on every aspect they could, without compromising difficulty. All of the moves that you preform make you feel like a ninja, especially in the escape sequences where you're tested on all of the mechanics that the game has thrown at you up until that point. The new boss fights were a great addition that I thought that the first game needed, and Moon Studios delivered. The bosses are tough, but a ton of fun to fight.

10/10. Another masterpiece from Moon Studios.
