RULES AND FEATURES
Try to survive 21 days on the Earth's satellite. As a result of the secret launch of the astronaut, and his subsequent emergency landing, due to a collision with some object, you and your hero were on the lunar surface. It's good that the astronaut survived, but..... As the authors of this game found out, there are not quite friendly elements on the Moon, rather even hostile ones. Of course, you sent a request for help to Earth, but the rescue will not arrive earlier than in three weeks. Survive!
