One, It would be perfectly understandable for someone to call her current condition a "Rape Cube".
That part may be…. over the line?
Two, They thought it would be okay if I just changed it from a woman to a man.
What is wrong with them? Ok look my opinion is that it really is not an ok part of the story. It seems a bit voyeuristic. Its not ok for a female character or a male one or even for 682 to experience this.
The fact was, they just couldn't consider the possibility of a woman being the cause of her own suffering.
I am ok with a character being the source of their own misery. I think your idea is great, the premise is good. But that said:
It was the part where she gambled too much and lost everything and got into overwhelming debt
I am loving this!
turned into a cube of flesh
Still good.
her various orifices co-located onto her surfaces
Weird but it can certainly be polished onto something creepy.
make it easier to violate her
that is just sloppy writing here, come on, the rape aspect is wrong. It's also too low-level shock. Come on you had good body horror going with the flesh cube.
I want to see this story flourish, to really grow. But that part diminishes it.
