I think there would be more to do for that in a larger project yea. At some point you have to hand yourself over to the rng of "did I move to a space with good stuff". Still though, giving the player too much information about where the good minerals are would remove the risk/reward decision "Do I move to another location and detect to find more and better rocks and risk the infection meter going up?". Which is why we did not include something like that. But good thoughts, thanks for playing!
