Turning my character around

I have a single sprite character, who I want to face the direction he's floating.

He only faces the left at the moment. How do I rig it up so it'll work that way?

In the animator bar, angle 0 means facing right, and angle 180 means facing left. So if you add two animation angles, then under each, draw a frame with the character facing in the appropriate direction. When you move the character it'll automatically pick the nearest animation frame for that direction.
