I've watched people play this game for a while and I finally went to play it myself on my desktop mac and it was for windows only. So I downloaded it and played it through Whisky but after the tutorial the games was pretty laggy and the frame-rate was low. This is one of the games that I've been wanting to play for a long time and a mac version would be a dream come true!

@potatowhale There is someone that created a new fork of whisky: https://github.com/leonewt0n/Bourbon it runs Steam and other games better than any other free solution for me so far.
