The easier way is simply download another mac game (or the previous mac version of this game), then download the window version, open both (for mac, right click the app & choose "show package contents"), delete everything in the app.nw folder in the resource folder of the mac version, then copy or move everything from the www folder from the window version to the mac version, then open terminal, use the chmod +x command on the app & it should be good to go. It'll crash a few times (so saves often) on launch, but will be running normally afterwards.OK, so, running this on a Mac from a terminal with nwjs.... weirdest damn thing. I can save the game, and in the save screen I can see my other saves and their metadata (elapsed game time, etc), and i can see them across restarts so some files are definitely being created. But the "load game" option in the main menu is never lit for me. Anyone got any guesses? The http-server output doesn't show the path, I did finds on all the places i could think of for new files with "sav" somewhere in the name, etc.
Gotta say, playing a porn game on what is effectively IronMan mode kinda sucks, you can't really take any risks....
This method will save you from booting up an actual server just to play a game.
