The 4-World Planet

The storyline: You are an astronaut. You go on a solo mission to a planet that was recently discovered. But the planet's gravity is stronger than you expected, so you are forced to perform a crash landing, damaging certain parts of your ship. You must explore the planet and find replacement parts, helping people and finding treasures along the way. You will periodically need to deal with things like getting hungry or thirsty. The game will warn you when you need to do something like eat or drink.
