So my friend was using this on linux and the game starts up all fine, music plays, the screens change in the menu but it doesn't react to any inputs and the mouse can only move
I figured this out. In the file "~/.config/unity3d/CAJJI/Control\ Room/Player.log" was a line telling that libgdk-x11-2.0.so wasn't found. So in Arch-based distros you can download the lib32-gtk2 package. If it wouldn't help, check the log file and install required package.
