I want to see grapple-platforming (like SCV-IV)

The one gameplay element I really want to see implemented in terms of the platforming for Bloodstained is the ability to grapple and swing from platform to platform with either a whip or a magic thread from Miriam’s curse markings. I want it to be skill-based, too, like it was in Super Castlevania IV, where you have to manually latch onto something, build momentum, and then time your release. (If it simply functions as a QTE, "slingshot-jump," or a "reel-me-in" Hookshot like in Zelda, that's not as engaging or versatile.) By having it like Super Castlevania IV, it would really add another dimension to platforming, which in turn adds another dimension to level design and exploration options. (It might even serve to speed up backtracking, or be used as a "safety net" in vertical areas where you might fall a good distance, so that you don't have to be perfect in climbing and re-climbing.) And when I say Super Castlevania IV, I do not mean the idea can't be taken further and evolved; I just want it to at least be as engaging as that older game.

...And since we're forging specific weapons in this game, maybe certain whips link to certain terrain types to swing to secret areas. You could extend that to the swords, too, in terms of breaking walls.
