I'm enjoying Ori overall but I 100% agree that in a post-Hollow Knight world, the combat just feels a little flat and consequence-free. When I saw that they had basically copied Hollow Knight's ability system wholesale, I was expecting to tweak my abilities for various encounters like I did in that game, but I've stuck with the same core abilities most of the way through and I've had zero difficulty (I could bump it up to hard, but I have to imagine that would just increase enemy health which wouldn't really address the issue).
That said, it's absolutely gorgeous and I'm enjoying the mobility quite a bit, especially once you get a few hours in and can zip around with triple jumps, gliding, etc.
