I can't even imagine how much effort would be, and I guess it has to be disheartening for the Dev, but as he said, it's his butt the one that is in the line of fire.
I have to agree tho, that the game suffered a major hit. It lost easily around 30% of the adult content (love and dark paths), and while a great effort was made to make the story keep its sense the plot holes are still visible.
Given that a re-render takes so much time (and being honest I don't think it's worth doing such a change), I'd love to see new characters, or add more scenes with the remaining LIs to "balance" the missing content.
Even with the plot holes, the story is still catchy and still makes sense, and I hope it improves once the law crisis is sorted. I'll definitely keep an eye on this game.
