You are on a moon.

The moon is small: the day/night cycle lasts 10 seconds.

The moon is very near to a sun: you cannot move during the day since you have to stay in a tent to protect you from sunrays.

You can only move during the night and you have to return to base without falling in a crater.

I would like to add "minerals" that you have to collect to repair your tent if I have some time tomorrow.
