bug i cant walk?

[Jasmine Pois]

for some reason at first it wouldn't let me walk at all but after restarting a few times i was able to walk, but i couldn't stop and to go a certain direction i had to angle my camera in a certain way. was wondering if anyone else is experiencing the same or similiar problem or if anyone knows whats wrong and how to fix it.
