Hello and welcome to the Forums Jig,
Please try Tigra's suggestion.
There are different controls for both your character and your camera. Moving your camera should not affect the direction your character moves in.
Please take a look at this link which shows you how you can view and change the in-game controls for your own preference.
How can I change my in-game controls?
Thanks
