The Ubuntu version is back up, and it is made only for ubuntu 18.04. If you want to try and play it on anything else, i can't say it will work. As most things go on linux, I cant even promise it will work on your system, but i play tested it, and it ran fine at 60 fps on Xubuntu 18.04. There is no controller support, nor will there ever be. I made this game to be played like a third-person shooter turned sideways. That being said, it does have controls written in the code through gamemaker 2's api. If it works awesome, if not, it's wasn't really supposed to. Audio groups have been pre-loaded, so hopefully it's not as intense as it used to be. There is a volume knob for sound FX and Music in the options menu, I suggest you set it to your personal preference.
Cheers!!
