In case you haven't done so yet, I'd generally recommend to go through a few of the tutorial series to learn the basics of ORK's workflow before delving into your own setup.
For this specific setup, you can use the Mouse player control type. The animations use a setup similar to the 2D tutorials (e.g. see here), i.e. you'll forward the movement speed to the animator controller as a parameter and use that in your blend tree to play idle and movement animations.
