It's not similar do Hollow Knight at all. They're in the same genre, but that's about it. Ori is a far shorter and more linear game, with indeed more focus on the platforming than the combat (like, way more). There's so little backtracking and revisiting older areas in Ori, and so little combat to do, that it feels more like a level-based platformer where the levels just so happen to connect to each other than a proper Metroidvania.
Good. So my guess is a 8-10 hours for the first time playing?
