How to make dynamic camera?

My game feels a little static and I decided to make the camera one that slightly moves toward the mouse cursor, how do you do that?

I feel like @JR01 would be the best person to ask for this kind of thing.

You should try a 2 subject camera between the player and the mouse (in game coordinates).

If that is too much movement, then I suggest placing the camera on a close orbit to the player. That way the player mostly stays at the center of the screen.
