Finished this the other day. I really like it, but I think the lack of difficulty really hurts how memorable the game is in comparison to its influences. I can't remember any of the fights with the Order because they're all so easy and don't really require much effort. It's a shame because their designs are great and the level design is really solid, but without the tough challenge to make you learn the levels and patterns, individual moments are a little more forgettable than they should be.
The last couple levels are really great though.
