For mobile: Top of the screen - move forward Left of the screen - turn left Bottom of the screen - move backwards Right of the screen - turn right Middle of the screen - do nothing For keyboard: W - move forward A - turn left S - move backwards D - turn right Change the slider to get thinner lines. This works best on Turbowarp.
