Thank you for paying attention and asking, I really wish to create the Mac and Linux version of the game so more peoples can enjoy.
But currently I don't have a PC with Mac or Linux OS and I need one for porting & testing the game.
As far as I know, Gamemaker won't allow you to create the other OS version if you don't have a PC with does OS.
So I'm trying to looking for the Virtual Machine that helps me to support Mac and Linux users right now. so I don't have to pay extra money for porting.
I will upload does versions of game as soon as I can when I figure it out how to do it.
I'm truly sorry that I can't give you the satisfying answer right now.
