Well opinion is rarely facts so it's alright.
You're more than welcome to pack down a version that works if it's not meant to be any hard as I'm certain you have some free time on your hands and knowledge about it, staff is being quite busy keeping up as of right now. There's many reasons why mac has been behind on game ports in many cases but for FeralHeart the main reason is that FH was only made for windows by the game creator, and there never were a native version for mac.
And well, that mac runs faster than windows doesn't have much to do w ith the question as of why most games come to windows, nor is it really true at all as as an operating system is just a part of it, and hardware and actual software inbetween is what really will matter.
