Darkout (Steam key).

http://store.steampowered.com/app/257050/
Crashed and alone on a world mankind tried to leave behind, Darkout challenges players to survive on Illuna, in harsh, procedurally generated biomes, utilizing the game’s sandbox features to build shelters, craft weapons, and research new technologies.

You are not alone. Light-sensitive creatures prowling the landscapes become most active at night and in a world shrouded by clouds the security of day will never come, instead, twilight periods allow players minor security to explore, rebuild, and gather resources.

Darkout’s deep history manifests itself through logs left behind by others, some recent, while others hearken back to long-extinct natives of Illuna, offering glimpses into what events led up to the pandemonium that now persists.
