Linux version is right here.

And the first trouble with it. Just note, you need OpenAl (tested on Ubuntu 16.04 x64) and, in general, everything is fine visually if you do not take into account the white thin strips on the edges of the screen in the menu (they gone away while playing). The bigger sore was just OpenAl. Well, maybe you understand "libopenal1" instead of "libopenal", I did not begin to delve into how to replace the reference. Because of this thing, there's no sound in the game(game trying to catch up a "libopenal.so". I hope you will be all right with this (in any case, the demo version is attached).
