Practice 30 moon landings with a simulator.
Change the gravity setting and successfully do it on the 31st try.
When Neil Armstrong did it, the final approach and landing were done "by the seat of your pants" --- there was no computer used. The de-orbit burn did use a primitive computer. The final approach and landing did not use a computer.
The craft was not flying (no air), it was translating.
There was no aerodynamic stability. - The was no aerodynamics.
When you successfully do it, post a screenshot. :)
That was one of the very first simulations written, when ported to a pdp-11 led to the development of Unix

42 is not a game. It is real open source orbital dynamics simulator with visualisation. You could debug and adjust real spaceflight with it.
