PannenKoek, Youtube’s foremost expert on Super Mario 64 esoterica, has made another video (35 minutes). This one’s about how they managed to get all the way up the tower in Whomp’s Fortress without pressing the A button at all.
To remind: not pressing the A is troublesome to build a challenge around (that being what makes it interesting) because it’s Mario’s most fundamental verb: the jump button. On the Gamecube, it was physically the biggest button! I loved that about its controller: these days I always get the buttons mixed up, as a result of some games making the left button the main one, and some making the bottom one. On the Gamecube, there was no question. But the A Button Challenge asks that you use it as little as possible.
The issue with Whomp’s Tower is that it’s a tower, a vertical structure itself atop a mountain. To find out how they did it, I refer you back to the video.
