Mario Kart Live: Home Circuit is now available on Switch, and countless players have been zipping around their homes having a blast. Most players would say that cats are the biggest challenge in playing the game, but Nintendo and Velan Studios actually had another unique issue to tackle during development. Nintendo's Hiroki Ikuta detailed the problem in an interview with Nintendo Life.
One issue we had was that when we lowered the speed of the kart to a level easy even for novice players to drive, the kart sometimes couldn’t run on carpet. To ensure players can enjoy Mario Kart Live: Home Circuit on a variety of different flooring, we implemented several ideas to cope with situations like that, such as making improvements to the hardware of the kart to increase torque, and taking data from the kart to work with the game and adjust the kart’s output.
