No, I did not enjoy it at all. I was immensely disappointed. I thought I would enjoy it when I saw that I had that option, to say that I like being tied up. But it turns out the MC's personality is far too set in stone for that option to make any sense. I'd honestly be less disappointed if I simply never had the option to even try to play the character I wanted.
If the options are literally nothing more than difficulty settings, then don't include any text besides the difficulty parameters. Nothing about them can be misconstrued that way.
If none of the endings should be construed as bad, then... uh... don't call them bad endings? I thought that would be obvious.
