Thanks!
Yea, I don't have a linux pc so I was already happy that the game ran on other people's linux PCs.
And I noticed that some people played on linux and had a stretched screen. I guess that's just how linux treats 4:3 in Unity. The only simple solution is windowed mode. Not sure how Wine does it though, because the demo runs pretty well with Wine on Mac. I had a native mac build before but it didn't want to show the textures but it worked fine using Wine and running the Windows build.
The controller detection is also an issue that some people had, and for other people it just worked. So it really depends on the system I guess. Linux and Mac is still a bit odd : P
But I'm glad you could play it and enjoy it : )
I remember the time that widescreen was a novelty, and even Windows games had problems dealing with it. But was just a matter of upgrading the video drivers to resolve the problem.
I don't know if there is a solution for Linux and Mac in this case. I've tested your game in my PC, which have the Nvidia proprietary drivers installed, and in my notebook, which only have the open source drivers. In both it runs the same way: stretched picture and no controller. That's a shame.
Anyways, thanks for the attention, for the answer and for this awesome demo! I will be waiting for the full release! :D
