arrow keys to move and turn and there are also WASD controls. btw, if you are on a low-end device ( such as a laggy school Chromebook) i would recommend turning RES to 16 and FOV to 30. If you are on a high end device ( such as like a Windows 10 or 11 computer or something then turn it on whatever you want ( highest quality is FOV 60 and RES 4)
