Well, what does it mean when someone says 'your game is sexist'?
Your game offends me as a woman/man/tumblr - in that case, well, I feel bad about it, but your opinion is going to be tabulated with all the other people that are/aren't offended by the game. Since I have received roughly zero complaints otherwise, trying to discover just what permutation of genders and races is less offensive is largely pointless.
Your game is actively supporting the societal system that keeps women/other oppressed gender/third oppressed gender down - Well that is fucking complicated to determine, isn't it. Well, probably, but I can't spontaneously cease to be white, male or Protestant, or will female programmers or musicians to come into existence nearby and aid me. (Believe me, i've tried.)
So, while I do appreciate the feedback (even if small and disconsiderate of the full context of the work) I'm not sure what I could do to make the issue go away.
