As it has been already said, nice atmosphere! I liked how you turned a basic exploration into a terror surprise.
The scanning minigame is quiere amusing, simple but effective, although it can get a bit too much if it goes beyond 3 stages. Bear in mind that the rewards must be associated with difficulty, so unless you can give a lot, it is better not to make the player take a great effort without knowing what the rewards will be.
The rover got stuck once in the middle of the air, but that was a minor problem that I could fix by resetting it a few times. What is most important is that you paid attention to moon's conditions; I've never been there but felt as if the lower gravity made movement different than on Earth (where I've been living lately).
