Following Whips
This idea struck my mind, That was that "Wouldn't it be cool to have whip looking things following after the Toris arms?" I think it's a nice idea. So basically, Following ropes that are on your wrists.
Replay ghosts
I called this "Replay ghosts" for the idea this wouldn't fit in in game gameplay. I really like how the ghost shows what you're about to do, And it truly is a game changer. So why not give it some love? A ghost that does the same thing you did around 50 frames behind you so you basically see two of yourself but the ghost would be faded out but still follow you in the same way. Another thing is that it could be turned off in game or just only show in replays.
'Rainbow' forces/relaxes
I thought maybe a color changing force, relax or anything that has a color in game could be cool to have a change in game, This is another idea that would suit replays more than in game, But I could see this work well with textures and in game also.
