Hey Accelerate,
If you changed the setting from the dialog box you should re-download the game so that it fixes. you can try and play with the 1 stick controller you should change the settings all the way at the bottom where it says P1_Horizontal and P1_Vertical I'm not sure how well this will work out. The game is made for dual stick controllers like the playstation or xbox gamepads.
Let me know if this works out for you thanks for the feedback,
Rafi
