Can't get the flipbook to face the direction my character is moving

Followed the tutorial that remakes the gameplay of Braid using Paper2D, but I don’t know if due different versions I can’t get my character sprite to face the direction I’m moving, it moves always facing the same direction, can you guys think of anything wrong with this? (“timesprite” is the flipbook)

I know it is a little late, but here is your answer. EDIT: Connect the InputAxis Move Right to Branch
