As previously discussed, Super Mario 3D World + Bowser's Fury is going to include a few gameplay tweaks over the Wii U release. Nintendo has now updated the official website for Super Mario 3D World + Bowser's Fury to share insight into those tweaks. You can see the official comments on speed boosts and gyro controls below.
"All characters have received a boost to their running speed and climb even higher after picking up a Super Bell, making platforming that little bit snappier. You can now also use gyro controls for certain sections of the game that previously required touch controls."
