Confusion with turning

Is it turning with no forward movement or still moving forward, just turning a little?

Rather then changing both x and y at the same time, it would have been better to only change one value while keeping the other the same. I would probably try five different tests (see below). That may seem like a lot, but it allows you to fully characterize the behavior and is a lot faster then changing multiple values at once and guessing which one caused what change. Once you've done those, you should be able to predict what would happen for any other combination.

x=0, y=0
x=0.25, y=0
x=-0.25, y=0
x=0, y=0.25
x=0, y=-0.25
