61 Days

61 Days is an adventure game set on the alien planet HB137F. After a spaceship crashes there, its crew finds that the atmosphere is survivable, but in exactly 61 days the temperature will fall to unbearable cold. You must find a way to keep the crew alive through the coming winter.

The expedition’s trail

A century earlier, an expedition on the planet perished after using alien technology to build fuel cells that generate heat and power. Your goal is to find these energy cells and use them to build a base before the temperature drops.

Challenges and decisions

The search involves platforming challenges, puzzles and fights. You also make decisions, sometimes as the ship’s captain, that affect the colony’s health and its chances of survival.
