To fix the mono issue just copy paste the folder from another unity project, it works
Though i've tried several times and the only thing i could figure out how to do was to grab things, i couldn't understand how the camera worked, nor how i was supposed to launch the probe as i couldn't even grab it, didn't seemed like there was any place to do such a thing as launch it, so yeah i couldn't get to play more than walking around and grab some stuff
