I played this game about 3 years ago i think? You play as a Teenage girl. You had to survive a set amount of time to evacuate the planet you are on (i assume earth but i honestly don't remember for sure) you had a set number of moves a day and you had a shelter that you had to fortify at night. There were a few characters and a few endings, some of which were pretty dark. Any help or suggestions would be apricated greatly.
