i mean if you use the grappling hook and press the button that makes you look behind you you will see the grappling hook and if you use grappling hook on a wall and then use another grappling hook you will move before it touch the wall
I think that's intentional?
Side note: I re-worked the Grappling Hook to be like BB+ so it'll be different than the beta tester version.
oh and also why you can only use one grappling hook
