Hehe, I tried to warn people in my devlog at launch. People are not always what they appear at first. Or at least, they aren't *just* that. So... give him a chance... or whoop his ass at the first opportunity, because you'll definitely get to face him in the ring at some point if you don't choose to tag team with him :D
As for intimacy preferences, there will be variety, there has to be. In a perfect world, I'd let you choose every time, but realistically, I simply don't think I can afford to invest in double the scene art for these moments :/
And crashing... please see if it happens again, and if you get an error message or something, post it in the discussion forum under "bug reports"? Did you not get further?
