Hey dude, I'll try to help you with this. I'm gonna take a look.
Last time I had a problem with movement, after which I've frozen my project.
I asked here for help, but no one did, I couldn't fix problem myself, so project was canceled.
I hope, that wont happen to your project, cause I'm willing to help you with your project wink
One thing I wanted to ask you about, why don't you use PhysX for this movement? It'll be better.
You can find example here:
PhysX for 2D sidescroller
Or in the AUM 100, it's called "Rigid for 2D".
