So yo just press space and it changes colours.You press the up arrow do change the back round to circles and press the down arrow to change it back and when you click the left arrow the back round will change to a random pattern back round and if you keep pressing the left arrow it will take you to different back round (Pattern). I know it's not good because I didn't have much time to do it. If it does not work when you click the space button just press it again and again and then it will work. Also press the green flag for something said by the letters lol Byee thanks for reading :)
