Hey switchers 'n' shooters!
I've just updated the game to a much more recent (and stable) version of Unity, which I'm hoping addresses some common problems among Linux users.
Version 1.3.5 is now available as a beta. See below for details on how to access it before full release.
If you've been playing on Linux and experiencing a white screen with no game visible, please try downloading the new patch (version 1.3.5) and let me know in the comments or discussions whether or not this patch fixes it.
This patch also includes D-pad support for Xbox One controllers, in addition to the existing analogue stick support.
To return to the normal version, just select "None" in step 4.
Please let me know if you have any issues with the new version.
Thanks!
Matt

P.S. Check out my upcoming game Dungeon Deathball. It's nearly finished!
