How do I make my game from my character's perspective?

I am trying to make a game that has my character’s eyes open and close and bounce as if he is walking… How do i do that?

If you’re looking for a 3D game maker, this isn’t one. It’s for up down left right games. I’ve made 3D shooters and short mazes, but there is no actual 3D. It’s just objects getting bigger as you push up.
