STUCK on Game Mechanics

I played Little Nightmares which I loved the aesthetic of it, and I’ve also been keeping an eye out for Omno for some time now. I’d figure movable platforms in a 3D platformer is a must, that’s why I’ve been thinking of doing not only this but figuring out how to give the player control over it in a fun, simple, and quick way, almost like how Mario uses his hat as a platform as well as many other things in Odyssey.
