There just aren't that many rape focused games that are actually good. Raptus would have been at the top but physical violence against women is a huge turn off for me. I like the fantasy of force without the reality that actually comes along with it.
That said blackheart skirts the edge...
Grinding (a little bit is ok)
Not knowing what to do to progress the plot
Bad writing - both plot and dialogue
But also too much writing even if it is good - an example is Triple Ex. It's well written but the banter just goes on and on...
I'd love to. I'm pretty confident in my writing and I studied art for a couple of years so I have two thirds of the skills needed. I just don't think I could be bothered to try to figure out coding and all that...
