I tried the experimental Linux build, and the screen only showed flashing colors. It's a old Unity error on Linux, solved by changing Resolution Width and Resolution Height on prefs file (1920x1080 in my case), located at /home/$USER/.config/unity3d/Unbound Creations/Headliner_ NoviNews/
After doing that fix the game works fine and i could finish it without any other problem.
Great game btw, makes you think twice about decision making in RL, ;)
