Yep, you cant se farther then 1m in the game, its unplayable on Linux right now. I'll need some time to fix this.
I just tried 0.9.5 (downloaded it before you took it down but hadn't tried it) and it seemed fine on my system. I didn't do any extensive testing, but I could see pretty far in game. SteamOS beta, Nvidia GeForce GTX 960 (415.27 drivers).

Actually I'm searching someone who wuld try out one new test build. This is just on level with varied shaders. Hopefully this wont be that "black" https://www.dropbox.com/s/03u67nqfomattx4/01.zip?dl=0 If you have time, please telle me, what you experienced. ;)
Tested it quickly on my work machine. An intel iGPU, so test was run in a 1280x720 window at a horrendous framerate, but seems like the bug is still there. Screenie below.
PS: First launch showed me a black screen for minutes after the unity logo, compiling shaders no doubt. Started quickly the second time.
EDIT: Errors in Unity's Player.log, maybe due to the iGPU?
The referenced script on this Behaviour (Game Object 'Light') is missing! (Filename: ./Runtime/Mono/ManagedMonoBehaviourRef.cpp Line: 333)
and
OpenGL Error: Invalid texture unit!
