I mean pressing left and right, as rotating along the Y axis almost guarantees you get rotation score because you never have the opportunity to not be facing the ground, as opposed to flipping along the X/Z Axis when using up and down arrows. There’s not much incentive to use Up and down arrows on their own other than to make sure you actually land at the very end of your air time. Maybe if turning horizontally was slower I think it’d counteract this, but like honestly it’s a very tiny detail for something that doesn’t affect my enjoyment!!
