The 4-World Planet is a text-adventure game, meaning that you control your character by typing commands; for example, if youre in a room with a door, you can type "open door" to open the door.
The storyline: You are an astronaut. You go on a solo mission to a planet that was recently discovered. But the planets 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.
Enhancements:
- Added fancier characters (curly quotes, em-dashes, etc.)
- Fixed grammar issues involving plural nouns
- The 4-World Planet is now a Universal Binary.
