The events in Ori and the Will of the Wisps occur directly after the first game, Ori and the Blind Forest (2015). Don't worry, it doesn't matter if you haven't played the first game—though it does help enhance the story.

The game is essentially a side-scrolling platformer that seems to be inspired by games of the past. However, this is no easy game; Ori and the Will of the Wisps makes you earn the victory at every stage. Forget the boss monsters, just the environment is enough to kill Ori. You will have to jump and time everything, including shifting of your powers, if you want to get anywhere.
