Ok, so I just get rid of the spikes/tentacles?

Or should I just replace it with something...weaker, maybe that the only things she can make the shadows interact with are herself (e.g, she can use the shadows to lift her up to reach a higher shelf or something, I don't really know)

That's up to you. If you want to try a different version/variation, that's up to you.

Ok, I'll edit the nerfed version in
