Is there any future where we'll return some of the old features of the game that made it (to me) better than it is now, like the enemies starting the sex animations when you're knocked down (or when the tentacles come up underneath you) and the game over cgs?

No, there isn't. I removed all non-con content from Crisis Point because I don't want to create that kind of content anymore. I won't ever be adding it back to Crisis Point, and it won't be in any future games I make either. I understand having a preference for the old content, this isn't intended to be kinkshaming or anything like that, but I won't be changing it back, so please respect that decision.
