I made a two-player reaction game with a microbit. I seem to have lost the image of it, but I can describe it the best I can. The game is a reaction game. When you first turn it on, it will show a face. Then when it changes, you have to slap the tin foil buzzer, the first person to press it gets a point. After that it shows your time and score, then goes again. You play as long as you want until it ends. Here is the code for it.
