You are the AI on NASA's futuristic Europa Moon Mission. Your job is to control the descent of the Lander from high altitude down to the designated landing zone.

Make sure to conserve as much fuel as possible! Your performance will be compared against other AI controllers. Your lander's thrusters can move it forward and backwards, rotate right and left, and move it up and down.

  • S: Move Backwards
  • A: Rotate Left
  • D: Rotate Right
  • Left mouse button: Gain height
  • Right mouse button: Lose height
