The terrain is an array in Data Memory rather than something read back out of the map, and that is the whole reason this is cheap: the ground under the lander is one index into 128 bytes, where asking the screen would be a transfer through the controller every frame. The column is the world position over eight, masked to the moon's 128. The surface is that column's row times eight - three turns left of the shift register, since a row is at most 24 and 192 fits in the low half. The feet are the lander's top plus its eight pixels. WHAT DECIDES IS THE SPEED AT THE MOMENT IT ARRIVES. Both of them, and both have to be gentle: three quarters of a pixel a frame downwards and half of one sideways. Sideways is the tighter on purpose, because a landing that was soft downwards and sliding is a lander on its side - which is the interesting half of the difficulty, and the half the drift bar was blind about until it existed. Two fixtures say it works, and they differ only in what was held: one holds nothing and falls the whole way, the other pulses the thruster six frames in sixteen and survives. Same terrain, same seed, same keys. Also: the gamepad did nothing, and the reason is that the four direction buttons are the D-PAD. A lot of controllers made this century have one nobody uses - the thumb goes on the stick, which reports as an axis rather than a button - so a pad that was plugged in and working correctly did nothing at all. The stick counts as held past halfway now. Untested here, because there is no controller in this environment and the suite runs headless; Voyager also says at startup which controllers it can see, so a pad that still does nothing can be told apart from one nothing noticed.
