It may be run from any terminal with a properly configured screen, and with a sufficiently fast baud rate. A planet, space stations, gravity, an atmosphere, friction, and fuel and temperature considerations all combine to complicate and enhance the game.
Acceleration is always forwards.
Your ship will begin to HEAT UP as you travel through the atmosphere. Your ship will automatically attempt to slow down and stop to reduce the temperature. The game then automatically restarts. At this point, you will be asked if you wish to play again. Thus, if your ship is near the planet, it will tend to fall inwards.
