A Button Challenge
The A Button Challenge is a Button Challenge for Super Mario 64. As the name would suggest, it is a challenge to beat the game using only the A button. The A button is used for jumping in game, which makes it the only move you can perform. In fact, you can't even start the game, as that requires the start button on the title screen. If you ignore this however, it makes the game quite a challenge, as you can only jump or double jump in place at the spawn position on the castle grounds. An anonymous user posted a video of the furthest anyone has gotten, being 15 units away from the spawn position via a misalignment squish bounce.
