Tijn’s post about Planetfall in the Space Quest forum just reminded me of this game.
It’s a really good sierra-style text parser graphical adventure with a really awesome, moody, lonely industrial space atmosphere.
I played it as an adult some time ago, and from memory the puzzles are challenging and there are a few ways to soft-lock yourself, but it’s mostly quite fair and there is little in the way of moon-logic.
The story is that you are sent alone to an asteroid mining colony in deep space that has lost contact with Earth and you have to find out what’s happened. Of course the whole place is abandoned and lurking with strange alien horrors!
