You can change your controls in the options. you can use the arrows keys to get to the options when you first get on. Downscroll means that the arrows will come down instead of up. reduce motion means that the camera and health bar and the arrows, including the ones that signal where you press or whatever, do not move. Show milliseconds means that it shows you how many milliseconds it took you to press the arrow. And then to change the actual controls you go down to them and press the space bar or tap in the middle of the screen and I forgot to say if you're on mobile to scroll up and down you tap at the top of the screen and the bottom of the screen.
All I did was add sunky in and his backround.
