In class my classmates and I all turned in a code, and made physical games that we played. My games was a three player game that would count down like 3,2,1 and then start. The three players would all compete to press their button first. Whoever pressed their button first would receive one point. If a player pressed their before the countdown would reset their points. Some of the troubles that I faced were pressing the buttons. Mr.Dembo explained to me that your body is like a circuit. In order for the circuit to work you needed to create a aluminum foil at the top of the cardboard. You then put your finger on the it to complete the circuit. Another problem that I ran into was the fact that the aluminum foil, for the buttons, were too thin and could easily be ripped. I solved this problem by adding more layers and thickness to prevent it from ripping easier. Here is the link https://makecode.microbit.org/#editor
