Thank you :)
The thing is, I startet this project in Game Maker 8 for Windows. Unfortunately it's not that easy to move it over to Game Maker Studio (which could support more platforms), because I'm using certain programming querks and addons that are not compatible.
I basically had to rebuilt the whole game from scratch in a newer engine.
But if there is a way to play .exe games in Linux you could maybe try it?
So planned for now is only Windows support, for other platforms I would need help to port it...
