This is the fastest I've ever seen!

Fun game! After climbing to 1 million feet, it took over 500,000 more to finally reverse direction with the ship pointed down and the engines firing. Unbelievable, the crater is visible from Earth Score: 869.4 point crash Speed: 7757.3mph Angle: 62.2° Time: 1319 seconds Flips: 0 Max speed: 7757.3mph Max height: 1549465ft Engine used: 11 times Boosters used: 351 times https://ehmorris.com/lander/

Well, my middle finger is numb, but I beat 1000 points. I took a straight path upward, and then switched to a horizontal -90° burn, slowly shifting to a -135° burn as I got closer to the ground.

Pretty fun! I like trying to make as many flips as possible: Basically a fender bender, but you landed Score: 45.4 point landing Speed: 3.5mph Angle: 9.5° Time: 62 seconds Flips: 18 Max speed: 86.8mph Max height: 1276ft Engine used: 32 times Boosters used: 55 times

My best is 22 flips. I did them on screen.

It would be nice if the "how to play" screen gave keyboard equivalents. I was about to give up trying to play until I saw someone's comment about arrow keys.

For me (Firefox, Linux) it did give keyboard instructions on the how to play screen.

The amazing thing is all these lunar lander games are harder than actually landing the lunar lander that landed on the moon. That's right it used a computer stabilized system and featured a fully automatic landing program however every lander was actually landed in the semi automatic mode where the pilot controlled the descent but the attitude was still maintained by computer.

And they used an analog computer to integrate and display the landing trajectory in real-time, just like in this game iirc.

Interesting talk about it and the landing process: https://youtube.com/watch?v=B1J2RMorJXM

I created a discrete (and less realistic) version of this concept here: https://qewasd.com/ ("Lunar Landing" challenge) - try to get a score as close to 0 as possible!

Some people have managed to use MILP solvers to optimally solve some of the other problems

Doesn't work for me. I can't get past "2 arrows at the same time". I press them, and see flame from both side thrusters, but the game doesn't register that I've done 2 arrows, and does not let me play. Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/110.0
