When I download to Linux and extract, I do not see any way to start the game. I see several .so objects, but no running script. How am I supposed to launch it?

Vox Gremory only has Vox Gremory.x86_64

I downloaded the linux version today. (R13)

After extracting the zip file, I tried to execute the VoxGremory.x86_64 file. My system said that it could not find a program yo open it with. There is a simple fix.

 In a gui, right click on the file, click properties, find a box that says "allow permission to execute this file" and make sure the box is checked. Than you should be fine to double click the file to start. (Note: depending on you distro and window manager, the checkbox might be worded different, but it should be similar to "allow executing this file."

If you prefer the command line... Change to the directory with the files and type:

chmod +x VoxGremory.x86_64

then type :

./VoxGremory.x86_64

to start
