Custom Rig Not Moving correctly

Im trying to make this starter character work correctly.

But it doesnt seem to move forward just backwards. I’ve already figured out that it has something to do with the feet, cause when i flip the humanoidrootpart, so the feet are pointing backwards, you can move forward just not backwards no more.

I’ve tried setting the body parts massless cause i thought it had to do with center of gravity. Tho that didnt do anything.
Thank you for any kind of help!
