Hi guys! Amazing tutorial!

I tried my best to follow along with the tutorial ( first 9 episodes ) but in the end, my Player is not moving ( he is just swaping left or right). I rewatched all the videos and redo all the code but it seems that I am not able to make it. My code is exactly the same as in the videos.

The only thing I noticed different is that the CharacterController2D has a checkbox that is ticked. I don't have that checkbox. I read that it appears only if we have Start or Update functions but you don't have them and it somehow appears..

I am using Unity 4.5.1.

Hope someone can help me out. Thanks!?
