Body physics

hey there!

I’m recently making a remake of the game hobbit rampage by games of gondor.

It’s a completley different game in the setting aspect.

but I chose the style becuase I knew it would work easiest for me.

The only problem I have is that I don’t know a decent way to make he character be able to rotate his upper body like in hobbit rampage.
I know it involves being able to find the mouse, but I don’t know how to make him rotate toward the mouse. I’ve looked at a bunch of tutorials and i still can’t figure it out. Can anyone help me?
