Guldplaneten
You start outside on the apron at a Danish spaceport, beside a 21-metre heavy lander you can walk underneath. Hop to the ladder, climb aboard, and run the start sequence — five switches and levers that light up in order — then the big red button. Fly the U-shaped yoke up through the atmosphere until the stars come out, pick Månen, Mars or Guldplaneten, jump through hyperspace, and fly down onto endless procedural mountains — then open the hatch and walk around outside, among the alien houses if you picked the gold one. Three flight modes, from an autopilot that flies and lands itself to full three-axis control. The ship cannot be broken. Every planet surface is an escape-time fractal, generated in the browser at load.
