You are stranded on a planet and you have no idea where it is. All of your crewmates are gone as is your ship. The only way to get rescued is to signal home. You have to search the planet for your crew and look for parts to signal home. Get around the planet by using the left and right arrow keys. You can jump by pressing 'Z' and you can interact with various things by pressing 'X'. Open your inventory with 'C.' You are probably going to want to pray, so push 'V' to do that. If you get stuck and need to kill yourself, press 'Q'. Good luck.
