The Lunar Lander

Here you pilot the Lunar Excursion Module and need to manage the the descent engine and the 6 thrusters. Ensure your speed and pitch are never in the red upon landing.

Also, this game models the inverse-square law for gravity (which basically means at the gravity is very weak at high altitude but strong when you are near the ground) so be careful not to send yourself off into deep space from which you'll (probably) never return.
