In an interview originally featured in Japanese strategy guides and now available on Shmuplations, the legendary developer and producer of Super Mario 64 discussed the game's development at length. When discussing playtesting, Miyamoto revealed that the team had a group of 10 middle schoolers, including his own child, play around on King Bob-omb's stage, Bob-omb Battlefield.

"Seeing him try dozens of times, over and over, to get up this unclimbable hill, as a parent I couldn't help but think, 'Geez, does this kid have any brains?'" Miyamoto laughed. Thankfully, the children's abilities (or lack thereof) aside, the playtest had been a success. "Afterwards we asked the children what they thought of the game, and they said it was fun, and that they wanted to play it again."
