If you wanna play games you should get Windows. :p
The game was made with Game Maker, so I guess it will run on WINE if other game maker games also run on WINE.
The developers are currently working on recoding the game without game maker. They do it because it's easily to cheat in a game maker game using the game maker game debugger. If the game will then also be available for other operating systems, depends on how they remake it, I guess.
