In the RC Car play section, the numbers 1889 and 2018 can be found under the cover of the controls. "2018" represents the year that Nintendo Labo released and "1889" refers to the year that Nintendo started as a company.

The idea for the game came from the fact that lead designer and director Tsubasa Sakaguchi wanted to make an interface that is interactive and something that is easy to grasp on. He initially planned for one player to use both Joy-Con controllers. However, the idea was later shot down because he thought it was too similar to using Wii Remote and Nunchuk. Sakaguchi almost considered having two players use one set of the controllers, but later scrapped it because it was too similar to the Famicom.

The Joy-Cons featured in the digital tutorials feature fully modeled interiors, despite these not being visible without orienting the camera to clip into the Joy-Con models.
