Some of you reported that the game is not working on Arch Linux.
I just updated the Linux version and it should be working fine.
If the game is starting in windowed mode instead of full screen, go to Options and try changing in some of the Window Modes and go back to full screen.
In the worst case it should be working fine in Windowed mode if it has issues in full screen. Full screen issue happens in some cases, I don't see it on my Linux.
More updates will be coming soon.
