A months ago since I played odyssey, but I'm pretty certain that there's multiple situations where you have to take control over others with the hat to progress the game. There's also moons to get with that mechanic.
Regarding some old discussion on Odyssey... I enjoyed it for what it was, just the same with Super Mario 3D World. I never played any of the other 3D Marios outside of a bit of Galaxy 1. I much prefer the 2D Mario games and thought New Super Mario Bros was really good on the Wii U. Haven't played the Switch version to know of any changes though.
